The FBI publishes Law Enforcement Officers Killed and Assaulted each year to provide information about the officers who were killed, feloniously or accidentally, and those officers who were assaulted while performing their duties. The FBI collects these data through the Uniform Crime Reporting (UCR) Program.
When reviewing the tables, charts, and narrative summaries presented in this publication, readers should be aware of certain features of the Law Enforcement Officers Killed and Assaulted (LEOKA) data collection process that could affect their interpretation of the information.
Beginning in 1937, the FBI’s UCR Program collected and published statistics on law enforcement officers killed in the line of duty in its annual publication, Crime in the United States. Statistics regarding assaults on officers were added in 1960. In June 1971, executives from the law enforcement conference, "Prevention of Police Killings," called for an increase in the FBI’s involvement in preventing and investigating officers’ deaths. In response to this recommendation, the UCR Program expanded its collection of data to include more details about the incidents in which law enforcement officers were feloniously killed and assaulted.
Using this comprehensive set of data, the FBI began in 1972 to produce two reports annually, the Law Enforcement Officers Killed Summary and the Analysis of Assaults on Federal Officers. These two reports were combined in 1982 to create the annual publication, Law Enforcement Officers Killed and Assaulted.
The deaths of the law enforcement officers that resulted from the attacks of September 11, 2001, are not included in the trend data in the tables of this publication. Because of the unique nature of the data from this singular event, including these extreme values in rate or trend data would skew data for most analyses.
For several years, the FBI’s UCR staff worked toward the goal of publishing all of its reports solely to the Internet, which removes many of the limitations of hard copy books without losing the value of the information being provided. Beginning with the 2005 edition, the FBI began producing Law Enforcement Officers Killed and Assaulted exclusively as a Web publication. That report, along with the subsequent publications, contain all the information that was published in previous years’ hard copy reports but with the benefits of navigable files and downloadable information.
