BRIEF FOR THE UNITED STATES
AS AMICUS CURIAE SUPPORTING PETITIONER

INTEREST OF THE UNITED STATES

This case presents the question whether a police offi cer who is participating in a lawful traffic stop may frisk a passenger when the officer has reasonable suspicion that the passenger is armed and dangerous but lacks reasonable suspicion that the passenger is committing or has committed a criminal offense. The Court's resolu tion of that question will affect the admissibility of evi dence in federal prosecutions. In addition, federal law enforcement officers regularly stop vehicles, and the conduct of those officers in that dangerous and recur ring situation will be governed by the Court's ruling in this case. Accordingly, the United States has a substan tial interest in the resolution of the question presented.

STATEMENT

1. On April 19, 2002, Officer Maria Trevizo and two other officers were on patrol in Tucson, Arizona, in an area close to a neighborhood associated with the Crips gang. At approximately 9 p.m., the officers pulled over a car after a license plate check revealed that the vehi cle's registration had been suspended for insurance-related reasons. As the officers made the stop, Officer Trevizo saw respondent, who was sitting in the back pas senger seat, look back at the officers' car, say something to the two people in the front seat, and continue looking back towards the officers. Pet. App. A2-A3 & n.1.

Once the car was stopped, one of the other officers instructed the occupants to keep their hands visible and directed the driver to get out of the car. The second officer approached the passenger side and spoke with the front-seat passenger, who remained in the vehicle. Pet. App. A3-A4.

Officer Trevizo approached the rear of the vehicle and made contact with respondent. Officer Trevizo was a member of a gang task force, and she observed that respondent was wearing clothing, including a blue bandana, that she considered consistent with Crips membership. J.A. 17. Officer Trevizo also saw that re spondent had a scanner in his jacket pocket, something she found highly unusual and of concern because a per son would not ordinarily carry a scanner "unless they're going to be involved in some kind of criminal activity or going to try to evade the police by listening to the scan ner." J.A. 16. In response to questions from Officer Trevizo, respondent provided his name and date of birth but said he did not have any identification. Respondent stated that he was from Elroy, Arizona, a place Officer Trevizo knew was home to a Crips gang. Respondent also said that he had served time in prison for burglary and had been out for about a year. Pet. App. A3-A4.

Officer Trevizo asked respondent to exit the vehicle and respondent complied. Pet. App. A4; J.A. 19, 35. After respondent was outside of the car, Officer Trevizo directed him to turn around and "patted him down for officer safety" because she "had a lot of information that would lead [her] to believe [respondent] might have a weapon on him." Pet. App. A4-A5 (first pair of brackets in original). During the pat-down, Officer Trevizo felt the butt of a gun near respondent's waist. Id. at A5. Respondent began to struggle, and Officer Trevizo placed him in handcuffs. Ibid.

2. Respondent was charged in state court with, inter alia, possession of a weapon by a prohibited possessor. He moved to suppress the evidence seized during the pat-down search, arguing that, even if Officer Trevizo had reasonable suspicion that respondent was armed, she lacked reasonable suspicion that he was engaged in criminal activity. J.A. 57-58. The trial court denied the motion, and a jury found respondent guilty on the fire arm charge. Pet. App. A5; J.A. 75-78.

3. A panel of the Arizona Court of Appeals reversed by a 2-1 vote. Pet. App. A1-A23.

a. The majority determined that respondent had been seized for Fourth Amendment purposes when the officers stopped the car in which he had been a passen ger. Pet. App. A8-A9 (citing Brendlin v. California, 127 S. Ct. 2400, 2410 (2007)). It also stated that Officer Trevizo could have "order[ed] [petitioner] out of the car after it had been stopped," id. at A11, and it "[a]s sum[ed], without deciding, that [Officer] Trevizo had reasonable suspicion that [respondent] was armed and dangerous," id. at A13-A14.

The majority concluded, however, that respondent's interaction with Officer Trevizo "had evolved into a con sensual encounter before [she] patted him down." Pet. App. A9; see id. at A14. According to the court, "a rea sonable person in [respondent's] position would have felt free to remain in the vehicle." Id. at A14. And relying on its own previous decision in In re Ilono H., 113 P.3d 696 (Ariz. Ct. App. 2005), the majority further concluded that "when an officer initiates an investigative encounter with a passenger that was consensual and wholly uncon nected to the original purposes of the routine traffic stop of the driver, that officer may not conduct a Terry frisk of the passenger without reasonable cause to believe 'criminal activity may be afoot.'" Pet. App. A15-A16 (quoting Terry v. Ohio, 392 U.S. 1, 30 (1968)); see id. at A6. The majority stated that it did "not * * * reach the broader question [of] * * * whether officers, in the interest of their own safety, and based solely on the sei zure resulting from the initial traffic stop, may routinely pat down passengers whom they suspect of no crime but whom they reasonably suspect might be dangerous." Id. at A15.

b. Judge Espinosa dissented. Pet. App. A17-A23. In his view, the majority erred in equating the pat-down of respondent with a situation in which police simply approach individuals in a park and then conduct a pro tective search for safety reasons alone. Id. at A18-A19 (discussing Ilono H.). Unlike in that case, the dissent reasoned, the frisk here "was preceded by a lawful traf fic stop based on founded suspicion." Id. at A19. And, the dissent believed, respondent was not free to leave at the time of the frisk. Ibid. The dissent thus concluded that "the majority ha[d] interpreted the facts of this case in a less than realistic fashion to essentially con clude that an officer reasonably fearing for her safety during a lawful roadside vehicle stop may not ensure her own safety and that of others present by patting down a suspicious passenger for weapons." Id. at A17.

4. The Arizona Supreme Court denied a petition for review. Pet. App. B1-B2.

SUMMARY OF ARGUMENT

The Arizona Court of Appeals erred in concluding that Officer Trevizo's pat-down of respondent violated the Fourth Amendment.

A. "The touchstone of the Fourth Amendment is rea sonableness," United States v. Knights, 534 U.S. 112, 118 (2001), and this Court has repeatedly recognized that traffic stops are "especially fraught with danger to police officers," Michigan v. Long, 463 U.S. 1032, 1047 (1983). Accordingly, the Court has held that officers may frisk the driver of a lawfully stopped vehicle if they have reasonable suspicion that the driver is armed and dangerous, see Pennsylvania v. Mimms, 434 U.S. 106, 112 (1977) (per curiam), and it has twice stated in dicta that the same rule applies with respect to passengers, see Knowles v. Iowa, 525 U.S. 113, 117-118 (1998); Long, 463 U.S. at 1047-1048. In Maryland v. Wilson, 519 U.S. 408 (1997), the Court held that "the rule * * * that a police officer may as a matter of course order the driver of a lawfully stopped car to exit his vehicle[] extends to passengers as well," id. at 410, and it did so based on the conclusion that the risks to officer safety posed by pas sengers are every bit as great as those posed by drivers, see id. at 413-414. Accordingly, the logic of this Court's cases inexorably produces the conclusion that an officer may frisk a passenger in a lawfully stopped vehicle if the officer has reasonable suspicion that the passenger is armed and dangerous.

B. The Arizona Court of Appeals erred in concluding that the constitutionality of the frisk in this case turns on whether a reasonable person in respondent's position would have felt free to terminate the encounter at the point when Officer Trevizo asked him to get out of the car. As an initial matter, on the facts of this case, a rea sonable person in respondent's position would not have felt free to leave at the time of the frisk. The stop of the car in which respondent was riding effected a seizure of him, and a reasonable person in his position would not have felt "free to depart without police permission." Brendlin v. California, 127 S. Ct. 2400, 2407 (2007). Nothing transpired during the interval between the ini tial stop and the frisk that would have communicated to a reasonable person that respondent was at liberty to move about as he pleased. Ibid.

In any event, this Court has never held that an offi cer may not perform a Terry frisk of a person reason ably believed to be armed and dangerous simply because the encounter was consensual until the point of the pat- down. To the contrary, the Court has repeatedly made clear that the societal interests in investigating crime and in protecting officer safety are distinct and that offi cer safety interests may justify certain actions that could not be justified solely to investigate crime.

The Arizona Court of Appeals' observation that po lice officers, like ordinary citizens, may simply avoid people they reasonably believe to be armed and danger ous is unrealistic. An officer often has the responsibility to enter dangerous situations and to investigate poten tially dangerous persons. The court's position also over looks the perverse incentives that its rule would give suspects, who could deter the police from approaching simply by arming themselves. In addition, the Arizona Court of Appeals erred in reasoning that a pat-down in a consensual encounter is prohibited because citizens generally have the right to refuse to speak with the po lice absent reasonable suspicion that they have engaged in unlawful conduct. When an individual chooses instead to remain in the presence of an officer, in a place where the officer has the lawful right to be, the fact that the individual is reasonably suspected of being armed and dangerous justifies the limited intrusion of a frisk for the officer's protection.

C. The rule adopted by the court of appeals would be particularly inappropriate in the context of traffic stops. This Court has repeatedly recognized the unique nature of traffic stops, both in terms of the reduced expecta tions of privacy enjoyed by drivers and passengers and the risks to officers while conducting such stops. Unlike an officer who initiates an on-the-street encounter, a police officer who makes a traffic stop will often be un able to assess the degree of danger until after making the stop. In addition, once a traffic stop is made, a pas senger in a stopped car may pose just as great of a po tential safety risk to an officer as the driver of the car. Likewise, an officer has no realistic way of avoiding one of the car's passengers, and the Court has recognized that it would be unreasonable to expect officers who are conducting traffic stops "to allow people to come and go freely" or to "move around in ways that could jeopardize [the officer's] safety." Brendlin v. California, 127 S. Ct. 2400, 2407 (2007). For that reason, the officer may or der the passenger out of the car and, if the facts provide reasonable suspicion that the individual is armed and dangerous, may conduct a protective frisk.

ARGUMENT

A POLICE OFFICER WHO IS PARTICIPATING IN A LAW FUL TRAFFIC STOP MAY PERFORM A BRIEF PAT-DOWN SEARCH OF ANY PASSENGER WHOM THE OFFICER HAS REASON TO BELIEVE MAY BE ARMED AND DANGEROUS

"[T]he central inquiry under the Fourth Amendment [is] the reasonableness in all the circumstances of the particular governmental invasion of a citizen's personal security." Terry v. Ohio, 392 U.S. 1, 19 (1968); see United States v. Knights, 534 U.S. 112, 118 (2001) ("The touchstone of the Fourth Amendment is reasonable ness."). This Court has repeatedly recognized that traf fic stops are "especially fraught with danger to police officers," Michigan v. Long, 463 U.S. 1032, 1047 (1983), and that "[t]he risk of harm to both the police and the occupants is minimized if the officers routinely exercise unquestioned command of the situation," Brendlin v. California, 127 S. Ct. 2400, 2407 (2007) (citations omit ted; brackets in original). As a result, officers who con duct traffic stops must have sufficient authority "to search for weapons and protect themselves from dan ger." Knowles v. Iowa, 525 U.S. 113, 117 (1998) (cita tions omitted). Accordingly, the Court has stated that officers who conduct "routine traffic stop[s]" may "per form a 'patdown' of a driver and any passengers upon reasonable suspicion that they may be armed and dan gerous." Id. at 117-118.

The Arizona Court of Appeals dismissed that clear statement from Knowles as "unexplained dicta." Pet. App. A15; see id. at A10 n.3. It then further concluded that, in situations where a traffic stop has "evolved into a separate, consensual encounter" with respect to a pas senger, a police officer "ha[s] no right" to frisk that pas senger for weapons, "even if [the officer] ha[s] reason to suspect [that the passenger is] armed and dangerous," unless the officer also has reasonable suspicion that the passenger has committed or is committing a crime. Id. at A14-A15.

That decision is seriously flawed and should be re versed by this Court. A police officer must have the ability to protect the officer's own safety from a person reasonably believed to be armed and dangerous when ever the officer encounters that person in a place where the officer has a lawful right to be. That principle has particular force in traffic stops, where officers inevitably seize passengers along with drivers and thus inevitably encounter dangerous individuals who are not suspected of any particular criminal activity. Accordingly, Officer Trevizo's frisk of respondent was constitutionally rea sonable regardless of whether at that point a reasonable person in respondent's position would otherwise have felt free to terminate the encounter and regardless of whether Officer Trevizo had reasonable suspicion that respondent was or had engaged in criminal activity.

A. A Police Officer May Frisk A Passenger During A Rou tine Traffic Stop If The Officer Has Reasonable Suspi cion That The Passenger Is Armed And Dangerous

The Arizona Court of Appeals did not question the lawfulness of the stop of the car in which respondent was a passenger. That stop effectuated a lawful seizure of respondent. See Brendlin, 127 S. Ct. at 2403, 2410 (holding that a passenger is seized "from the moment [the] car [comes] to a halt on the side of the road" and thus "may challenge the constitutionality of the stop"). The Arizona Court of Appeals also assumed for purposes of its decision that Officer Trevizo "had reasonable sus picion that [respondent] was armed and dangerous." Pet. App. A13-A14.1 Those premises alone establish the constitutionality of a frisk for weapons.2

1. In Terry v. Ohio, supra, this Court observed that "a perfectly reasonable apprehension of danger may arise long before [a police] officer is possessed of ade quate information to justify taking a person into custody for the purpose of prosecuting him for a crime." 392 U.S. at 26-27. Noting the large number of law en forcement personnel who have been killed in the line of duty, id. at 23-24, the Court stated that "it would be un reasonable to require that police officers take unneces sary risks in the performance of their duties," id. at 23. Accordingly, the Court held that "there must be a nar rowly drawn authority to permit a reasonable search for weapons for the protection of the police officer, where he has reason to believe that he is dealing with an armed and dangerous individual." Id. at 27; see id. at 24. The Court emphasized that "[t]he officer need not be abso lutely certain that the individual is armed" and that "the issue is whether a reasonably prudent man in the cir cumstances would be warranted in the belief that his safety or that of others was in danger." Id. at 27.

In Pennsylvania v. Mimms, 434 U.S. 106 (1977) (per curiam), this Court held that "once a motor vehicle has been lawfully detained for a traffic violation, the police officers may order the driver to get out of the vehicle without violating the Fourth Amendment's proscription of unreasonable searches and seizures." Id. at 111 n.6. The Court concluded that the government's "legitimate and weighty" interest in officer safety outweighed the "de minimis" additional intrusion of requiring a driver who has already been lawfully stopped to exit the car. Id. at 110-111. Then, applying the principles announced in Terry, the Court further held that a driver who has exited the vehicle may be patted down for weapons if a reasonable officer could conclude that the driver is "armed and thus pose[s] a serious and present danger to the safety of the officer." Id. at 112.

In Maryland v. Wilson, 519 U.S. 408 (1997), the Court held that "the rule * * * that a police officer may as a matter of course order the driver of a lawfully stopped car to exit his vehicle[] extends to passengers as well." Id. at 410; see id. at 415. The Court acknowl edged that whereas "[t]here is probable cause to believe that the driver has committed a minor vehicular offense, * * * there is no such reason to stop or detain the pas sengers." Id. at 413. But the Court emphasized that "traffic stops may be dangerous encounters," ibid., and it stated "that the possibility of a violent encounter stems not from the ordinary reaction of a motorist stopped for a speeding violation, but from the fact that evidence of a more serious crime might be uncovered during the stop," id. at 414. As a result, the Court con cluded that "the same weighty interest in officer safety is present regardless of whether the occupant of the stopped car is a driver or passenger." Id. at 413.

2. As this Court stated in Knowles, see 525 U.S. at 117-118, Terry, Mimms, and Wilson together establish that a police officer who is conducting a routine traffic stop may always order a passenger to get out of the car and may perform a brief pat-down search for weapons if the officer has reasonable suspicion that the passenger is armed and dangerous. Terry explains that a police officer's "more immediate interest * * * in taking steps to assure himself that the person with whom he is dealing is not armed with a weapon that could unexpect edly and fatally be used against him" is distinct from the more general "governmental interest in investigating crime." 392 U.S. at 23; see id. at 26-27. Wilson states that a passenger's "motivation * * * to employ vio lence" is "every bit as great as that of the driver," 519 U.S. at 414, and it expressly equates drivers and passen gers for purposes of a police officer's ability to order them out of the car "as a matter of course," id. at 410. Drivers and passengers should therefore be treated the same on the related issue of whether, once a person is out of a stopped car, an officer may perform a brief pat- down in order to protect the officer's own safety. See Long, 463 U.S. at 1047-1048 (stating in dicta that Mimms "held that police may order persons out of an automobile during a stop for a traffic violation, and may frisk those persons for weapons if there is a reasonable belief that they are armed and dangerous") (emphases added).

As was the case with drivers in Mimms, the Court "need not * * * go so far as to suggest that an officer may frisk [the passengers] of any car stopped for a traf fic violation." 434 U.S. at 110 n.5. Instead, the Court need only apply in this particular context Terry's "controll[ing]" holding that an officer may conduct a protective frisk in circumstances where the officer could reasonably conclude that a person with whom the officer is dealing "[i]s armed and thus pose[s] a serious and present danger to the safety of the officer." Id. at 111- 112.3 The courts of appeals that have confronted that specific question have uniformly held that a police offi cer may perform a pat-down search of a passenger who has been ordered out of a car as part of a lawful traffic stop if the officer has reasonable suspicion that the pas senger is armed and dangerous.4

B. The Arizona Court Of Appeals' Conclusion That Respon dent Was No Longer Seized At The Time Of The Frisk Does Not Warrant A Different Result

The Arizona Court of Appeals concluded that it need not decide "whether officers, in the interest of their own safety, and based solely on the seizure resulting from [an] initial traffic stop, may routinely pat down passen gers whom they suspect of no crime but whom they rea sonably suspect might be dangerous." Pet. App. A15. Instead, the court held that the "initial lawful seizure of [respondent] incident to the traffic stop of the driver [had] evolved into a separate, consensual encounter" by the time Officer Trevizo asked respondent to step out of the car. Id. at A14. The court then further held that, under those circumstances, the Fourth Amendment barred Officer Trevizo from conducting a pat-down search for weapons unless she also had reasonable suspi cion that respondent was or had engaged in criminal activity. Id. at A6, A14-15.

The court of appeals' reasoning is incorrect. The question whether a particular encounter is consensual involves whether a reasonable person in the position of the person with whom an officer is dealing would feel free to terminate the encounter and depart the scene without interference by the officer. See, e.g., Brendlin, 127 S. Ct. 2405-2406; Florida v. Bostick, 501 U.S. 429, 435-436 (1991). The answer to that question, however, has no bearing on whether a police officer who is in a place where the officer has lawful authority to be may take appropriate steps to protect the officer's own safety. Rather, Officer Trevizo's "legitimate and weigh ty" (Mimms, 434 U.S. at 110) interest in protecting her self from a person she had reasonable suspicion was armed and dangerous had the same urgency regardless of whether a reasonable person in respondent's position would have felt free to leave or whether Officer Trevizo also had reasonable suspicion that respondent was or had engaged in criminal activity.

1. As an initial matter, the Arizona Court of Appeals' conclusion that respondent was no longer seized when Officer Trevizo frisked him is legally incorrect. In Brendlin, this Court stated that "any reasonable passen ger" would understand that, once a car is stopped, "no one in the car [is] free to depart without police permis sion." 127 S. Ct. 2406-2407. The court of appeals was correct that an involuntary detention may evolve into a consensual interaction, see Pet. App. A9, but its opinion fails to demonstrate that that is what occurred here.

First, the court stated that the interaction had been "cooperative" until Officer Trevizo frisked respondent and that "her questions to him were wholly unrelated to the purpose of the traffic stop." Pet. App. A11. But po lice officers are obviously not required to adopt a hostile tone with people they have detained, and this Court has held that officers may ask questions that are unrelated to the justification for an initial seizure so long as they do not prolong the seizure's length. See Muehler v. Mena, 544 U.S. 93, 100-101 (2005). Second, the court of appeals cited Officer Trevizo's testimony about her pur poses in speaking with respondent and her opinion about whether respondent could have refused her request to get out of the car. Pet. App. A8-A9. But the test for whether a person has been or remains seized is an "ob jective" one and does not depend on "the motive of the police for taking" certain actions or the "subjective" be liefs of individual officers. Brendlin, 127 S. Ct. at 2408- 2409. Finally, the court of appeals noted that "neither [Officer] Trevizo nor the other officers ordered all the occupants to get out of the vehicle during the traffic stop for officer safety reasons" and that "the front seat pas senger remained in the car throughout the encounter." Pet. App. A12. The court of appeals did not explain how those facts would have conveyed to a reasonable person in respondent's position that he was "free to decline [Of ficer Trevizo's] request[]" that he get out of the car, Brendlin, 127 S. Ct. at 2406 (citation omitted), and there is no apparent reason why they would have done so.

Because, as Brendlin recognizes, the stop of a car communicates to a reasonable passenger that the pas senger is not free to terminate the encounter with the police and move about at will, an officer must take some action to communicate to the passenger that the passen ger is free to leave. Nothing occurred in this case that would have sent that message.5

2. a. In any event, this Court has never held that a police officer's ability to conduct a Terry frisk is contin gent upon the officer having reasonable suspicion that a person with whom the officer is dealing has committed or is committing a crime. To the contrary, the Court has repeatedly reaffirmed the basic principle that it is con stitutionally reasonable for officers who have reasonable concerns for their own safety to take protective mea sures.

The Court's opinion in Terry does not state that an officer's ability to conduct a pat-down is limited to situa tions where the officer has reasonable suspicion that a potentially armed and dangerous person is committing or has committed a crime. Terry applied the Fourth Amendment's general reasonableness standard to "two independent actions, each requiring separate justifica tions." United States v. Flippin, 924 F.2d 163, 165 n.2 (9th Cir. 1991). First, Terry concluded that a police offi cer may make an investigatory stop-that is, halt a per son's movement and require the person to remain in the officer's presence for a brief period-so long as the offi cer has reasonable suspicion that the person is engag ing, or has engaged, in criminal activity. 392 U.S. at 21, 30-31. Second, the Court held that, even "in situations where [an officer] may lack probable cause for an ar rest," the officer may perform a limited pat-down search for weapons "where he has reason to believe that he is dealing with an armed and dangerous individual." Id. at 24, 27. In so holding, the Court specifically distin guished between "the governmental interest in investi gating crime"-the justification for an investigatory stop-and a police officer's "more immediate interest * * * in taking steps to assure himself that the person with whom he is dealing is not armed with a weapon that could unexpectedly and fatally be used against him"- the justification for a frisk. Id. at 23. In short, "Terry did not cabin the use of officer safety patdowns to lawful investigatory detentions." United States v. Orman, 486 F.3d 1170, 1173 (9th Cir. 2007).

This Court's post-Terry decisions have reiterated that an officer's interest in protecting the officer's own safety is distinct from-and may justify actions that could not be supported by reference to-the general societal interest in investigating crime. In Michigan v. Summers, 452 U.S. 692 (1981), for example, the Court described Terry as having "approved a 'frisk' for weap ons as a justifiable response to an officer's reasonable belief that he was dealing with a possibly armed and dangerous suspect." Id. at 698 (emphasis added); see Ybarra v. Illinois, 444 U.S. 85, 93 (1979) (stating that, under Terry, "a law enforcement officer, for his own protection and safety, may conduct a patdown to find weapons that he reasonably believes or suspects are then in the possession of the person he has accosted"). In Michigan v. Long, supra, the Court stated that its decisions establish "that protection of police and others can justify protective searches when police have a rea sonable belief that the suspect poses a danger," 463 U.S. at 1049, and it applied that principle to hold that officers may perform a protective sweep of those places in a vehi cle's passenger compartment that may conceal a weapon whenever they have a reasonable belief that the driver of the vehicle poses a danger, id. at 1045-1051.

In Maryland v. Buie, 494 U.S. 325 (1990), the Court held that police officers who have apprehended the sub ject of an arrest warrant within a home may conduct a protective sweep of any areas that they have reasonable suspicion may "harbor[] an individual posing a danger to the officer or officers." Id. at 327. The Court acknowl edged that, once the subject of the warrant has been found, "the search for him [i]s over, and there [i]s no longer that particular justification for entering any rooms that ha[ve] not yet been searched." Id. at 333. But the Court stated that officers possess an independ ent interest "in taking steps to assure themselves that the house in which a suspect is being, or has just been, arrested is not harboring other persons who are danger ous and who could unexpectedly launch an attack." Ibid. And the Court said nothing to suggest that a police offi cer's entitlement to frisk someone the officer encounters during a Buie sweep turns on whether the officer has reasonable suspicion that the person has committed a crime. To the contrary, the Buie Court described Terry and Long as having been "concerned with the immediate interest of the police officers in taking steps to assure themselves that the persons with whom they were deal ing were not armed with, or able to gain immediate con trol of, a weapon that could unexpectedly and fatally be used against them." Ibid. (emphasis added).

This Court's decision in Mimms further undermines the Arizona Court of Appeals' conclusion that a police officer's ability to conduct a pat-down search for weap ons depends on whether there is "reasonable cause to believe the suspect may have committed a crime." Pet. App. A15. Nothing about the process of writing a cita tion for a minor traffic violation would ordinarily require ordering the driver to get out of the car. Yet this Court made clear in Mimms that an officer's ability to impose that "incremental intrusion" (434 U.S. at 109) does not depend on whether the "objective observable facts * * * support a suspicion that criminal activity [is] afoot." Id. at 108 (citation omitted).

b. In addition, the Arizona Court of Appeals' conclu sion that the constitutionality of the frisk in this case depends on whether respondent was still at that point seized as part of the initial traffic stop cannot be recon ciled with this Court's decision in Wilson. The question in Wilson was whether an officer may order a passenger to exit a stopped vehicle in the absence of reasonable suspicion as to the passenger. Although the Court stated that "as a practical matter, the passenger[] [is] already stopped by virtue of the stop of the vehicle," 519 U.S. at 413-414, the Court found it unnecessary in Wil son to decide whether a passenger is "seized" as a con stitutional matter when the car is initially pulled over. See Brendlin, 127 S. Ct. at 2406 (stating that the Court's previous decisions had not "squarely answered" that question). An officer's entitlement to order the driver and passengers out of a stopped car and to conduct a Terry frisk are justified by precisely the same interest: ensuring the safety of those to whom society entrusts enforcement of its laws. Yet, under the Arizona Court of Appeals' view, an officer's ability to conduct the frisk would turn on precisely the same question-that is, whether a passenger is "seized" at a given point during a traffic stop-that the Court found unnecessary to reach in order to resolve the former issue in Wilson.

c. None of this Court's other decisions is to the con trary. In United States v. Place, 462 U.S. 696 (1983), the Court noted that Terry "implicitly acknowledged the authority of the police to make a forcible stop of a person when the officer has reasonable, articulable suspicion that the person has been, is, or is about to be engaged in criminal activity." Id. at 702. In support of that reading of Terry, the Court quoted language from Justice Harlan's concurring opinion that argued that police offi cers must be entitled to make a forcible stop based on less than probable cause because, in Justice Harlan's view, "if the frisk is justified in order to protect the offi cer during an encounter with a citizen, the officer must first have constitutional grounds to insist on an encoun ter, to make a forcible stop." Id. at 702 n.4 (quoting Terry, 392 U.S. at 32 (Harlan, J., concurring)). But the Court was not required to, and did not, adopt that gloss on Terry's holding in order to decide Place, because the defendant in Place had "refused to consent" to either his luggage's initial detention or its subsequent search. Id. at 699.

The same is true of Adams v. Williams, 407 U.S. 143, 146 (1972), and Florida v. J.L., 529 U.S. 266, 272, 274 (2000). Adams did not state that an officer is entitled to conduct a pat-down only "[s]o long as the officer is enti tled to make a forcible stop," 407 U.S. at 146, and the Court expressly noted that the government had not ar gued that the pre-frisk encounter in that case had been consensual, id. at 146 n.1. Consent was similarly not at issue in J.L., because the approaching officers ordered the defendant to place his hands on a wall and immedi ately frisked him. 529 U.S. at 268; see id. at 274 ("We speak in today's decision only of cases in which the offi cer's authority to make the initial stop is at issue") (em phasis added).

3. The Arizona Court of Appeals and other courts that have reached the same conclusion have offered sev eral arguments in support of the view that it is constitu tionally unreasonable for a police officer to "conduct a pat-down search during a consensual encounter if the officer lacks reasonable suspicion that criminal activity is occurring, even if the officer has reason to believe a suspect may be armed and dangerous." Pet. App. A6. None is persuasive.

First, the court of appeals reasoned that because "[a]ny person, including a policeman, is at liberty to avoid a person he considers dangerous," a police officer may simply refrain from approaching a potentially armed and dangerous individual unless the officer also has reasonable suspicion that the person has committed or is committing a criminal offense. Pet. App. A8 (quot ing Terry, 392 U.S. at 32 (Harlan, J., concurring)); see In re Ilono H., 113 P.3d 696, 700 (Ariz. Ct. App. 2005). The court of appeals made no effort to explain, however, how that principle would work in practice when a poten tially dangerous individual-for example, a person who appears to be a bodyguard or, for that matter, a passen ger in a car-remains in the immediate vicinity of a per son, such as the driver, whom the officer reasonably sus pects of specific criminal activity. The officer cannot choose to avoid the passenger without abandoning the officer's legitimate investigatory pursuit of the driver, which is plainly an unreasonable outcome.6

More fundamentally, the argument that police offi cers can simply avoid dangerous people ignores the na ture of an officer's job. "Asking questions is an essential part of police investigation," Hiibel v. Sixth Judicial Dist. Ct. , 542 U.S. 177, 185 (2004), and good police work will often require an officer to venture into places or situations that private citizens might sensibly choose to avoid. Because "consensual encounter[s] * * * impli cate[] no Fourth Amendment interest," Florida v. Ro driguez, 469 U.S. 1, 5-6 (1984) (per curiam), the rule adopted by the court of appeals would encourage those who wish to avoid any contact with the police to arm themselves so as to deter officers from approaching them in the absence of particularized suspicion of unlaw ful conduct. This Court has previously refused to con strue the Fourth Amendment to create precisely those sorts of "perverse incentives." Scott v. Harris, 127 S. Ct. 1769, 1779 (2007); see ibid. (declining "to lay down a rule requiring the police to allow fleeing suspects to get away whenever they drive so recklessly that they put other people's lives in danger"). Cf. California v. Hodari D., 499 U.S. 621, 627 (1991) (stating that because "[s]treet pursuits always place the public at some risk, * * * compliance with police orders to stop should therefore be encouraged").

Second, the Arizona Court of Appeals reasoned that permitting a brief pat-down search for weapons in the absence of reasonable suspicion of criminal wrongdoing would be "inconsistent with" the principle that "a person is allowed to disregard or flee from a consensual encoun ter with law enforcement officers." Pet. App. A7-A8; see Ilono H., 113 P.3d at 700; see also Terry, 392 U.S. at 33 (Harlan, J., concurring); United States v. Gray, 213 F.3d 998, 1000 (8th Cir. 2000). Citizens may as a general mat ter decline to interact with a police officer in the absence of reasonable suspicion that they have engaged or are engaging in criminal wrongdoing. A person who has consented to speak with an officer may also-in the ab sence of reasonable suspicion-choose to terminate the encounter and depart the scene in a manner that does not threaten the safety of the officer or others in the vicinity. But neither of those propositions establishes that a person whom an officer has reason to believe may be armed and dangerous has a right both to remain in the presence of an officer in a place where the officer has lawful authority to be and to be immune from a lim ited pat-down search designed to ensure the officer's safety. Such a rule would compel police officers either to retreat from places where they have lawful authority to be or to expose themselves to unreasonable risks.

Finally, some courts have emphasized that, whereas a consensual encounter does not implicate the Fourth Amendment at all, "[a] protective frisk is both a search and a seizure for Fourth Amendment purposes." Gray, 213 F.3d at 1000; see State v. Giltner, 537 P.2d 14, 16 (Haw. 1975). But the Fourth Amendment does not say that searches and seizures may be conducted only for the purpose of investigating crime. Rather, "[t]he fun damental command of the Fourth Amendment is that searches and seizures be reasonable." New Jersey v. T.L.O., 469 U.S. 325, 340 (1985); see Florida v. Jimeno, 500 U.S. 248, 250 (1991); Terry, 392 U.S. at 19. And this Court has repeatedly recognized that the compelling interest in officer safety will sometimes make it consti tutionally reasonable for police officers to take actions that cannot be justified by reference to society's more general interest in enforcing the criminal law. See pp. 12-13, 16-19, supra; see also Brigham City v. Stuart, 547 U.S. 398, 400 (2006) (holding that "police may enter a home without a warrant when they have an objectively reasonable basis for believing that an occupant is seri ously injured or imminently threatened with such in jury").

C. Traffic Stops Provide A Particularly Compelling Con text For Recognizing An Officer's Authority To Frisk A Suspicious Passenger Who Remains On The Scene

For the reasons stated above, the Arizona Court of Appeals erred in concluding that a police officer's ability to frisk a person whom the officer has reasonable suspi cion is armed and dangerous turns on whether the offi cer's encounter with that person has been consensual until the point of the frisk and, if so, whether the officer nonetheless has reasonable suspicion that the person has committed or is committing a crime. In any event, such a rule would be especially unwarranted in the par ticular context of traffic stops.

This Court has long noted that "[p]assengers, no less than drivers, possess a reduced expectation of privacy" when traveling in cars. Wyoming v. Houghton, 526 U.S. 295, 303 (1999). An automobile "seldom serves as one's residence or as the repository of personal effects," and it "travels public thoroughfares where both its occu pants and its contents are in plain view." New York v. Class, 475 U.S. 106, 112-113 (1986) (citation omitted). A person's reasonable expectation of privacy when travel ing in a car is further diminished by the government's "pervasive regulation" of automobiles, id. at 113, and by the possibility of "traffic accidents that may render all [of a car's] contents open to public scrutiny," Houghton, 526 U.S. at 303.

In addition, traffic stops differ from on-the-street encounters in numerous respects. This Court has re peatedly recognized that traffic stops "are especially fraught with danger to police officers," Long, 463 U.S. at 1047,7 and an officer who makes a traffic stop will of ten be unable to assess the degree of danger until after making the stop. The officer may have difficulty deter mining how many people are in a vehicle before it has come to a halt on the side of the road. See Wilson, 519 U.S. at 414 (stating that the "danger to an officer * * * is likely to be greater when there are passengers in ad dition to the driver"). The vehicle's body and seats may make it impossible to detect weapons or other indicia of danger until the officer reaches the car. And whereas an officer who wishes to approach a particular person in a public place could, at least in certain circumstances, wait until that person is no longer in the company of another person whom the officer considers armed and danger ous, a police officer cannot realistically avoid a passen ger in a lawfully stopped vehicle.

The Court has already recognized that the degree of danger posed by a passenger during a traffic stop does not depend on whether the officer has reason to believe that the passenger has committed a crime. See Wilson, 519 U.S. at 413-414. The degree of danger posed by a particular passenger likewise bears no necessary rela tionship to whether a reasonable person in the passen ger's position would feel free to terminate the portion of the encounter that involves the passenger or whether a passenger who exits the vehicle does so voluntarily or at the direction of the officer. Danger may still exist even when an encounter has become consensual and no other crime is suspected, as this Court has recognized. Cf. Long, 463 U.S. at 1050 ("If a suspect is 'dangerous,' he is no less dangerous simply because he is not arrested.").

This case illustrates the point. Respondent's contin ued observation of the officers as they approached, his apparent gang colors, his possession of a portable scan ner useful to intercept police band communications, his prior conviction, and his residence in a place known for a particular gang, J.A. 12, 16-21, reasonably led a trained officer to be concerned for her safety, even though she could not put her finger on particular crimi nal activity in which he was involved, J.A. 36. In that situation, an officer must be permitted to conduct a frisk to protect against sudden deployment of a weapon. In deed, the Arizona Court of Appeals' decision would cre ate the absurd result that a passenger who, after the completion of a traffic stop, exits the car and begins moving towards an officer in a manner that the officer reasonably perceives to be threatening could not be frisked for weapons unless the officer also has reason able suspicion that the passenger has already committed a crime.

This Court's decision in Brendlin further under scores that there are important differences between traffic stops and on-the-street encounters. In Brendlin, the Court held that a passenger is "seized" for Fourth Amendment purposes when an officer stops the car in which the passenger is traveling. 127 S. Ct. at 2403. In reaching that conclusion, the Court stated that a reason able person in the passenger's position "would not ex pect a police officer to allow people to come and go freely from the physical focal point of an investigation into faulty behavior or wrongdoing" or "let people move around in ways that could jeopardize [the officer's] safety." Id. at 2407. The Arizona Court of Appeals' opinion, however, is expressly premised on the notion that, because the encounter had become consensual, Officer Trevizo was constitutionally required to give respondent an opportunity to depart the scene after he exited the vehicle without first ensuring that, in so do ing, she was not permitting a dangerous person to get behind her. Such a regime would be a far cry from the "unquestioned command of the situation" that this Court has stated will best minimize "[t]he risk of harm to both the police and the occupants" of a stopped car.

CONCLUSION

The judgment of the Arizona Court of Appeals should be reversed.

SEPTEMBER 2008

1 Respondent has acknowledged that the question upon which this Court granted review "is premised on the claim that [Officer] Trevizo reasonably suspected [respondent] to be armed and dangerous." Br. in Opp. 15; see Pet. i. The question presented further presumes that Officer Trevizo lacked reasonable suspicion that respondent "[was] committing, or ha[d] committed, a criminal offense." Pet. i. The record supports the first proposition and nothing justifies questioning the State's concession on the second proposition. Cf. United States v. Leon, 468 U.S. 897, 905 (1984) (accepting the court of appeals' conclusion that probable cause for a warrant was absent where the government did not seek review of that holding).

2 Respondent's assertion that the frisk was constitutionally invalid because Officer Trevizo was not actually motivated by officer safety in performing it, see Br. in Opp. 5, 7, 11, is without merit. "An action is 'reasonable' under the Fourth Amendment, regardless of the individual officer's state of mind, as long as the circumstances, viewed objectively, justify the action. The officer's subjective motivation is irrelevant." Brigham City v. Stuart, 547 U.S. 398, 404 (2006) (internal quotation marks, brackets, and citation omitted); accord Ohio v. Robinette, 519 U.S. 33, 38 (1996).

3 Although this Court has analogized traffic stops to Terry stops for certain purposes, see Knowles, 525 U.S. at 117; Long, 463 U.S. at 1051; Mimms, 434 U.S. at 110-112, it has taken care to avoid "suggest[ing] that a traffic stop supported by probable cause may not exceed the bounds set by the Fourth Amendment on the scope of a Terry stop." Berkemer v. McCarty, 468 U.S. 420, 439 n.29 (1984). Because the police conduct in this case was fully consistent with Terry, the Court need not determine how much additional latitude officers possess during a stop that is supported by probable cause.

4 See, e.g., United States v. Soares, 521 F.3d 117, 119-122 (1st Cir. 2008); Holeman v. City of New London, 425 F.3d 184, 191-192 (2d Cir. 2005); United States v. Moorefield, 111 F.3d 10, 13-14 (3d Cir. 1997); United States v. Colin, 928 F.2d 676, 678 (5th Cir. 1991); United States v. Montgomery, 377 F.3d 582, 586 (6th Cir. 2004), cert. denied, 543 U.S. 1167 (2005); United States v. Hernandez-Rivas, 348 F.3d 595, 599 (7th Cir. 2003); United States v. Woodall, 938 F.2d 834, 837 (8th Cir. 1991); United States v. Vaughan, 718 F.2d 332, 335-336 (9th Cir. 1983); United States v. Dennison, 410 F.3d 1203, 1211 (10th Cir.), cert. denied, 546 U.S. 955 (2005); see also United States v. Howard, 151 Fed. Appx. 221, 224 (4th Cir. 2005) (per curiam), cert. denied, 546 U.S. 1145 (2006).

5 The question whether respondent remained seized at the time of the frisk appears "fairly included [with]in" (Sup. Ct. R. 14.1(a)) the question upon which the Court granted review. See Pet. i. If the Court were to disagree with the Arizona Court of Appeals' resolution of that issue, the question would still remain whether the frisk was consistent with the Fourth Amendment. It was. See pp. 9-13, supra.

6 Nor can the officer solve the problem by ordering the passenger to leave the area. A passenger whom the officer reasonably suspects of being armed and dangerous cannot be trusted to obediently leave the scene. (Nor, even if the passenger would leave the scene, would it be good police work to order a person reasonably believed to be armed and dangerous to go back into society at large.) And officers should not have to divert their attention from the business of a traffic stop to mon itor the activities and movements of passengers who were ordered to disperse but may choose to return. Cf. Brendlin, 127 S. Ct. at 2407 ("[T]he risk of harm to both the police and the occupants is minimized if the officers routinely exercise unquestioned command of the situa tion.") (citation omitted).

Robinson, 414 U.S. 218, 233-234 & n.5 (1973); Adams, 407 U.S. at 148 n.3.
