Monitoring Police with Body-Worn Cameras: Evidence from Chicago
Using data from the Chicago Police Department on complaints filed by civilians and reports of force filed by officers, this paper estimates the effect of body-worn cameras (BWCs) of officer and civilian behavior. Using a two-way fixed effects design, I find BWCs are associated with a 29% reduction in use-of-force complaints, driven by white officer-black civilian complaints. Additionally, I find a 34% reduction in officers reporting striking civilians and a large though less significant reduction in officer firearm usage, potential mechanisms for the reduction in complaints. Importantly, I find no change in officer injury or force from civilians. However, I find evidence of de-policing as officers make fewer drug-related arrests following BWC adoption.
期刊介绍:
The Journal of Urban Economics provides a focal point for the publication of research papers in the rapidly expanding field of urban economics. It publishes papers of great scholarly merit on a wide range of topics and employing a wide range of approaches to urban economics. The Journal welcomes papers that are theoretical or empirical, positive or normative. Although the Journal is not intended to be multidisciplinary, papers by noneconomists are welcome if they are of interest to economists. Brief Notes are also published if they lie within the purview of the Journal and if they contain new information, comment on published work, or new theoretical suggestions.
