United States Department of Justice. Federal Bureau of Investigation
Since 1930, the Federal Bureau of Investigation has
compiled the Uniform Crime Reports (UCR) to serve as a periodic
nationwide assessment of reported crimes not available elsewhere in
the criminal justice system. Each year, this information is reported
in four types of files: (1) Offenses Known and Clearances by Arrest,
(2) Property Stolen and Recovered, (3) Supplementary Homicide Reports
(SHR), and (4) Police Employee (LEOKA) Data. The Police Employee
(LEOKA) Data provide information about law enforcement officers killed
or assaulted (hence the acronym, LEOKA) in the line of duty. The
variables created from the LEOKA forms provide in-depth information on
the circumstances surrounding killings or assaults, including type of
call answered, type of weapon used, and type of patrol the officers
