The Metropolitan Police Department of the District of Columbia (MPD) partnered with The Lab @ DC to design and implement a randomized controlled trial (RCT) to examine the effects of MPD's body-worn camera (BWC) program. Eligible officers in public-facing roles were randomly assigned to wear BWCs in accordance with MPD's BWC policy (treatment group) or not wear BWCs (control group). Over 2,220 MPD members participated, making this study the largest RCT examining the effects of BWCs to date. Using administrative data, we compare control and treatment groups to determine if BWCs have an effect on police use of force, civilian complaints, policing activity, and judicial outcomes. The pre-analysis plan is available at https://osf.io/yjyng/.
