National Data on Citizen Complaints About Police Use of Force

Abstract

National data on citizen complaints about police use of force were collected by the Bureau of Justice Statistics (BJS) in 2003 and 2007. These data are a critical component of the Department of Justice’s (DOJ) overall response to 42 USC 14142, which requires the Attorney General to “acquire data about the use of excessive force by law enforcement officers.” The BJS data have the potential to help support democratic policing, provide baseline data on use of force for comparative statistical reporting and research purposes, and enable strong local checks on police abuses, provided their validity and reliability can be demonstrated. This study sought to assess the validity and reliability of the BJS data. Findings indicate that the BJS data suffer from serious measurement flaws, do not provide a valid and reliable basis for comparative statistical reporting and research purposes, and should not be relied on for purposes of litigation.
