The Justice Department is moving forward with plans to collect data on how often law enforcement officers use force and how often civilians die during encounters with police or while in police custody. Demands for more complete data surfaced in particular in the last two years amid a series of high-profile deaths of black men at the hands of police officers, with the federal government unable to say reliably how often fatal encounters occurred across the country. The FBI plans to begin a pilot program early next year that would gather more complete use-of-force data, including information on cases that don't result in death. The earliest participants would be the largest law enforcement agencies, as well as major federal agencies such as the FBI, the Drug Enforcement Administration and the Bureau of Alcohol, Tobacco, Firearms and Explosives. The program would then be expanded to include additional agencies across the country, which would be expected to regularly disclose whether a use-of-force instance resulted in death, injury or a firearm discharge at or in the direction of a person. Though there's no legal requirement for law enforcement agencies to provide information on police force that doesn't result in death - the 2014 Death in Custody Reporting Act covered only interactions in which individuals died - the Justice Department said it's requesting local agencies to disclose details on even nondeadly encounters. Reporting of nondeadly encounters would remain voluntary.
