This brief describes the results of the Urban Institute’s evaluation of the Milwaukee Police Department’s body-worn camera program. From October 2015 to December 2016, the Milwaukee Police Department (MPD) deployed body-worn cameras (BWCs) in a phased rollout to all of its roughly 1,100 patrol officers. Through a randomized controlled trial of 504 officers, the Urban Institute found that those who wore BWCs conducted fewer subject stops and were less likely to receive a complaint than officers who were not equipped with cameras. However, BWCs had no effect on whether officers engaged in use of force during the study period.
