Law Enforcement Management and Administrative Statistics (LEMAS), 2016
  • Description:The Law Enforcement Management and Administrative Statistics (LEMAS) survey collects data from a nationally representative sample of general-purpose agencies (i.e., local and county police departments, sheriffs' offices, and primary state police agencies). The 2016 LEMAS sample design called for the survey questionnaire to be sent to 3,499 general purpose law enforcement agencies, including 2,640 local and county police departments, 810 sheriffs' offices, and the 49 primary state police departments (Hawaii does not have a primary state police agency). The design called for all agencies employing 100 or more full-time equivalent sworn personnel to be included with certainty (self-representing), and for smaller agencies to be sampled from strata based on number of full-time equivalent sworn officers and type of agency. A total of 28 local police departments were determined to be out-of-scope for the survey because they had closed, had less than one full-time equivalent sworn officer, had contracted out their services with another law enforcement agency, or only had special enforcement responsibilities. The final mail out total of 3,471 agencies included 2,612 local police departments, 810 sheriffs' offices, and the 49 state agencies.

Law Enforcement Management and Administrative Statistics Body-Worn Camera Supplement (LEMAS-BWCS), 2016
  • Description:Beginning in 2016, the Law Enforcement Management and Administrative Statistics (LEMAS) survey adopted a core and supplement structure. The LEMAS core has been conducted every 3 to 4 years since 1987 with approximately 3,200 local, county and state law enforcement agencies across the United States. Due to the breadth of the survey, detailed analysis of any specific law enforcement topic cannot be done with the LEMAS core. The LEMAS supplements are designed to fill this void by allowing for a more comprehensive examination on a key topic in law enforcement and are administered in between core years. The 2016 LEMAS Body-Worn Camera Supplement (LEMAS-BWCS) is the first supplement administered under the new structure.

Law Enforcement Response to Human Trafficking and the Implications for Victims in the United States, 2005
  • Description:The purpose of the study was to explore how local law enforcement were responding to the crime of human trafficking after the passage of the Trafficking Victims Protection Act (TVPA) in 2000. The first phase of the study (Part 1, Law Enforcement Interview Quantitative Data) involved conducting telephone surveys with 121 federal, state, and local law enforcement officials in key cities across the country between August and November of 2005. Different versions of the telephone survey were created for the key categories of law enforcement targeted by this study (state/local investigators, police offices, victim witness coordinators, and federal agents). The telephone surveys were supplemented with interviews from law enforcement supervisors/managers, representatives from the Federal Bureau of Investigation's (FBI) Human Trafficking/Smuggling Office, the United States Attorney's Office, the Trafficking in Persons Office, and the Department of Justice's Civil Rights Division. Respondents were asked about their history of working human trafficking cases, knowledge of human trafficking, and familiarity with the TVPA. Other variables include the type of trafficking victims encountered, how human trafficking cases were identified, and the law enforcement agency's capability to address the issue of trafficking. The respondents were also asked about the challenges and barriers to investigating human trafficking cases and to providing services to the victims. In the second phase of the study (Part 2, Case File Review Qualitative Data) researchers collected comprehensive case information from sources such as case reports, sanitized court reports, legal newspapers, magazines, and newsletters, as well as law review articles. This case review examined nine prosecuted cases of human trafficking since the passage of the TVPA. The research team conducted an assessment of each case focusing on four core components: identifying the facts, defining the problem, identifying the rule to the facts (e.g., in light of the rule, how law enforcement approached the situation), and conclusion.

  • Description:The goal of this research project was to enhance the understanding of Asian battered women's experiences in seeking help from the criminal justice system (CJS) and other (non-CJS) programs and develop recommendations for system responses to intimate partner violence (IPV) in Asian communities. The project focused on selected Asian ethnic groups -- Filipina, Indian and Pakistani and addressed the following research questions: When do Asian battered women experience various types of IPV over their life course? When do Asian battered women come into contact with CJS and non-CJS agencies? What kinds of responses do Asian battered women receive from CJS and non-CJS agencies? What responses do Asian battered women perceive as helpful? What are the barriers to contacting CJS agencies? What suggestions do Asian battered women have for improving CJS responses to IPV in Asian communities?

Line Police Officer Knowledge of Search and Seizure Law: An Exploratory Multi-city Test in the United States, 1986-1987
  • Description:This data collection was undertaken to gather information on the extent of police officers' knowledge of search and seizure law, an issue with important consequences for law enforcement. A specially-produced videotape depicting line duty situations that uniformed police officers frequently encounter was viewed by 478 line uniformed police officers from 52 randomly-selected cities in which search and seizure laws were determined to be no more restrictive than applicable United States Supreme Court decisions. Testing of the police officers occurred in all regions as established by the Federal Bureau of Investigation, except for the Pacific region (California, Oregon, and Washington), since search and seizure laws in these states are, in some instances, more restrictive than United States Supreme Court decisions. No testing occurred in cities with populations under 10,000 because of budget limitations. Fourteen questions to which the officers responded were presented in the videotape. Each police officer also completed a questionnaire that included questions on demographics, training, and work experience, covering their age, sex, race, shift worked, years of police experience, education, training on search and seizure law, effectiveness of various types of training instructors and methods, how easily they could obtain advice about search and seizure questions they encountered, and court outcomes of search and seizure cases in which they were involved. Police department representatives completed a separate questionnaire providing department characteristics and information on search and seizure training and procedures, such as the number of sworn officers, existence of general training and the number of hours required, existence of in-service search and seizure training and the number of hours and testing required, existence of policies and procedures on search and seizure, and means of advice available to officers about search and seizure questions. These data comprise Part 1. For purposes of comparison and interpretation of the police officer test scores, question responses were also obtained from other sources. Part 2 contains responses from 36 judges from states with search and seizure laws no more restrictive than the United States Supreme Court decisions, as well as responses from a demographic and work-experience questionnaire inquiring about their age, law school attendance, general judicial experience, and judicial experience and education specific to search and seizure laws. All geographic regions except New England and the Pacific were represented by the judges. Part 3, Comparison Data, contains answers to the 14 test questions only, from 15 elected district attorneys, 6 assistant district attorneys, the district attorney in another city and 11 of his assistant district attorneys, a police attorney with expertise in search and seizure law, 24 police academy trainees with no previous police work experience who were tested before search and seizure law training, a second group of 17 police academy trainees -- some with police work experience but no search and seizure law training, 55 law enforcement officer trainees from a third academy tested immediately after search and seizure training, 7 technical college students with no previous education or training on search and seizure law, and 27 university criminal justice course students, also with no search and seizure law education or training.

Linking Theory to Practice: Examining Geospatial Predictive Policing, Denver, Colorado, 2013-2015
  • Description:This research sought to examine and evaluate geospatial predictive policing models across the United States. The purpose of this applied research is three-fold: (1) to link theory and appropriate data/measures to the practice of predictive policing; (2) to determine the accuracy of various predictive policing algorithms to include traditional hotspot analyses, regression-based analyses, and data-mining algorithms; and (3) to determine how algorithms perform in a predictive policing process. Specifically, the research project sought to answer questions such as: What are the underlying criminological theories that guide the development of the algorithms and subsequent strategies? What data are needed in what capacity and when? What types of software and hardware are useful and necessary? How does predictive policing "work" in the field? What is the practical utility of it? How do we measure the impacts of predictive policing? The project's primary phases included: (1) employing report card strategies to analyze, review and evaluate available data sources, software and analytic methods; (2) reviewing the literature on predictive tools and predictive strategies; and (3) evaluating how police agencies and researchers tested predictive algorithms and predictive policing processes.

Lone Offender Terrorists and Mass Murderers in the United States between 1990 and 2013
  • Description:The study examines the behavioral underpinnings of three types of United States-based offenders: solo terrorists, lone-actor terrorists, and individuals who engage in mass casualty violence but lack an ideological motivation (aka mass murderers). In particular, the researchers compare the developmental, antecedent behavioral, and ideological factors that crystallize within the offender and are later expressed behaviorally via an attack. The data address the following research questions: What are the similarities and differences between lone actor terrorists and solo mass murderers, in terms of sociodemographic characteristics and behavioral traits prior to, during, and after their attack? Can risk factors associated with delinquency and criminal offenses also help predict low-likelihood, high impact events such as lone actor terrorist attacks and mass murders? Do these factors remain the same over time? To complete the research objectives, the researchers used an open source methodological design, relying solely on text materials available within the public domain. Data were coded and then statistically analyzed using bivariate and multivariate tests. The sample (n = 186) was limited to United States-based offenders who operated between 1990 and 2013 and were identifiable through publicly available materials.

Lone Wolf Terrorism in America: Using Knowledge of Radicalization Pathways to Forge Prevention Strategies, 1940-2013
  • Description: These data are part of NACJD's Fast Track Release and are distributed as they were received from the data depositor. The files have been zipped by NACJD for release, but not checked or processed. Users should refer to the accompanying readme file for a brief description of the files available with this collection and consult the investigator(s) if further information is needed. Typically, NACJD's Fast Track Release requires all direct identifiers to be removed or masked. As the sources of information for this collection are publicly available, direct identifiers were left within the collection. This study created the largest and most comprehensive database ever created to date on lone wolf terrorism. It includes 1 Excel data file (LONEWOLF_NIJ_HAMM_SPAAIJ_2014_unlocked.xlsx; n=98, 23 variables). The information was gathered from an extensive review of previous research, biographies and memoirs, journalistic sources, government reports, court documents, encyclopedias and documentary films. Qualitative interviews were conducted as part of this research, but these interviews were not made available for archiving.

Long-Range Planning Survey of Federal Judges, 1992: [United States]
  • Description:In October 1992, the Federal Judicial Center surveyed nearly all federal judges on a wide range of issues of concern to the federal courts. The survey was conducted for two purposes: to inform the deliberations of the Judicial Conference Committee on Long-Range Planning and to provide information for the Center's congressionally-mandated study of structural alternatives for the federal courts of appeals. Although the purposes were distinct, the areas of interest overlapped, resulting in a survey instrument that addressed many issues at differing levels of detail. The survey questions dealt with the nature and severity of problems in the federal courts, structure and relationships, jurisdiction size and resources, administration and governance, discovery, juries, criminal sanctions, deciding appeals in the current system, availability and compensation of counsel, and methods of civil dispute resolution.

Long-Term Consequences of Delinquency: Child Maltreatment and Crime in Early Adulthood in New York, 1990-2006
  • Description:The purpose of the study was to expand understanding of the long-term consequences of juvenile delinquency by describing the prevalence and frequency of two adult outcomes -- arrest and the perpetration of abuse and neglect -- within a gender-diverse sample of known offenders. The researchers also sought to better inform the development and provision of services targeted to delinquent youth in residential care by exploring whether characteristics assessed at intake into care predict adult offending risk. The research team tracked a large sample of delinquent boys and girls released from juvenile correctional facilities/programs in New York State in the early 1990s and used state administrative databases to document their involvement with criminal justice and child protective services in young adulthood. Sample youth were initially drawn from a research database originally created to examine short-term criminal recidivism rates and associated risk factors among known juvenile delinquents (Frederick, 1999). As part of that study, a comprehensive list of adjudicated delinquents discharged from the custody of the New York State (NYS) Division of Youth between January 1, 1991, and December 31, 1994, was generated. The research team selected a stratified, random subsample of 999 youths with case reviews and tracked them forward through time from age 16 to age 28. The Administrative/Case File Review Data (Part 1) contain information on the experiences prior to being admitted into state custody of 999 youths. Specifically, Part 1 includes early risk factors taken from items coded during the initial recidivism study conducted by Frederick (1999). Part 1 also includes information on a youth's childhood experiences with child welfare services collected by the research team as part of this study. Information on a youth's prior receipt of child welfare services was obtained by extracting records from the NYS Child Care Review Service system (CCRS). The Child Protective Services Reports Data (Part 2) contain information on the sampled subjects' involvement with Child Protective Services (CPS) as young adults (ages 16-28). CPS data were collected by conducting person-based searches of CONNECTIONS, the NYS Statewide Automated Child Welfare Information System. For Part 2, adult perpetration of child maltreatment outcome data were collected on a total of 1,543 child protective services (CPS) reports. The Criminal History Data (Part 3) contain information on the sampled subjects' early adult involvement (ages 16-28) with the NYS adult criminal justice system. The research team documented adult crime and perpetration of child abuse and neglect via searches of two independent state administrative databases: (1) the NYS Offender-Based Transaction Statistics Computerized Criminal History (OBTS/CCH) database, which records all New York state-based arrests of individuals age 16 or older from point of arrest through disposition and sentencing; (2) the Department of Correctional Services (DOCS) database, which tracks all New York State prison admissions and discharges. For Part 3, data were collected on a total of 6,627 adult arrest events. Part 1 contains 30 variables detailing information on the study participants, including demographic variables and variables related to offense history, individual functioning, child maltreatment, receipt of child welfare services, and family environment. Part 2 includes 22 variables derived from child protective services (CPS) reports linked to a study participant, including variables relating to the participant's perpetration of child maltreatment, type of alleged maltreatment, investigation outcome, and outcome variables reflecting participants' involvement in various types of maltreatment allegations. Finally, Part 3 of the study contains 147 variables derived from specific adult arrest events associated with the participants, including arrest-specific variables, case outcome variables, and criminal history variables.
