Controversial police use of pressure incidents have spurred protests throughout the nation and requires reform. Physique-worn cameras (BWCs) have acquired in depth consideration as a possible key answer. I conduct the primary nationwide research of the consequences of BWCs in additional than 1,000 companies. I establish the causal results by utilizing idiosyncratic variation in adoption timing attributable to administrative hurdles and the prolonged course of to the eventual adoption at totally different companies. This empirical technique addresses limitations of earlier research that evaluated BWCs inside a single company; in a single-agency setting, the management group officers are additionally not directly affected by BWCs as a result of they work together with the therapy group officers (spillover), and companies that give researchers entry might basically differ from different companies (site-selection bias). Overcoming these limitations, my multi-agency research finds that BWCs have led to a considerable drop in the usage of pressure, each amongst whites and minorities. Nationwide, they cut back police-involved homicides by 43%. Surprisingly, I don’t discover proof that BWCs are related to de-policing. Inspecting social media utilization knowledge from Twitter in addition to knowledge on the Black Lives Matter (BLM) motion, I discover that after BWC adoption, public opinion towards the police improves. These findings indicate that BWCs might be an vital device for bettering police accountability with out sacrificing policing capabilities.
