Body Worn Cameras

Recent use-of-force events have led law enforcement agencies, citizens, civil rights groups, and city councils to push for the rapid adoption of body-worn camera (BWC) technology. Within less than a decade, BWCs have transformed from a technology that received little attention by many police leaders and scholars to one that has become rapidly prioritized, funded, and diffused into local policing. Below are the reports on this subject by faculty from the Center for Evidence-Based Crime Policy.
