Research on body‐worn cameras

Research Summary In this article, we provide the most comprehensive narrative review to date of the research evidence base for body‐worn cameras (BWCs). Seventy empirical studies of BWCs were examined covering the impact of cameras on officer behavior, officer perceptions, citizen behavior, citizen perceptions, police investigations, and police organizations. Although officers and citizens are generally supportive of BWC use, BWCs have not had statistically significant or consistent effects on most measures of officer and citizen behavior or citizens’ views of police. Expectations and concerns surrounding BWCs among police leaders and citizens have not yet been realized by and large in the ways anticipated by each. Additionally, despite the large growth in BWC research, there continues to be a lacuna of knowledge on the impact that BWCs have on police organizations and police–citizen relationships more generally. Policy Implications Regardless of the evidence‐base, BWCs have already rapidly diffused into law enforcement, and many agencies will continue to adopt them. Policy implications from available evidence are not clear‐cut, but most likely BWCs will not be an easy panacea for improving police performance, accountability, and relationships with citizens. To maximize the positive impacts of BWCs, police and researchers will need to give more attention to the ways and contexts (organizational and community) in which BWCs are most beneficial or harmful. They will also need to address how BWCs can be used in police training, management, and internal investigations to achieve more fundamental organizational changes with the long‐term potential to improve police performance, accountability, and legitimacy in the community.
