1563. Investigative Jurisdiction -- Assault On Federal Officer

All assaults on, kidnapping of, and murders of Federal officers will be investigated exclusively by the Federal Bureau of Investigation (FBI) except:

  1. The FBI does not, at the request of the Treasury Department, investigate assaults on, kidnapping of, or murders of any Treasury Department personnel. This includes Secret Service, Bureau of Alcohol, Tobacco and Firearms (BATF), Internal Revenue Service (IRS), and Customs. However, if the Bureau believes that its absence from a case is materially affecting the interests of justice, it is to call this to the attention of the Attorney General.
  2. In accordance with an agreement between the Postal Service and the Justice Department, investigative jurisdiction of offenses in Postal Service buildings against postal laws, or involving, among other things, offenses committed by postal employees, is with the Postal Service inspectors. Thus, the responsibility for investigating the large majority of cases involving postal employees that can be expected to arise under 18 U.S.C. § 111 will be with the postal inspectors. FBI investigation of assaults on, kidnapping of, and murders of Postal Service employees is limited to the following three situations: (1) assaults, kidnapping, or homicides of postal employees which are incidental to some other crime which is within the investigative jurisdiction of the FBI; (2) assaults, kidnapping, or homicides of Postal Inspectors believed to have been committed by persons who are not employees of the Postal Service; (3) in any other situation where the FBI is directed by the Department of Justice to investigate.
