The Federal Bureau of Investigation’s (FBI’s) Law Enforcement Officers Killed and Assaulted (LEOKA) Program publishes annual data on law enforcement fatalities in the United States based on submissions from U.S. local and state agencies through the Uniform Crime Reporting (UCR) process, as well as from groups such as Concerns of Police Survivors and the National Law Enforcement Officers Memorial Fund. The FBI also contacts agencies directly for supplemental information on officer fatalities.
