In this report, RAND Corporation researchers summarize what is currently known about killings committed by police officers in the United States and identify existing evidence about various ways to prevent these killings. A relatively large body of research on these topics exists, but these studies often suffer from methodological shortcomings, largely stemming from the dearth of available data. Recognizing the need for more-rigorous work to guide efforts to reform police — and, more specifically, to reduce police killings — the authors present work focused on the development of a research agenda, or a road map, to reduce police killings. The report, based on an extensive literature review as well as interviews with policing experts, contains a series of recommendations for areas in which research efforts may be most effective in helping inform policy-making and decision-making aimed at reducing police killings.

The authors identified six focus areas — foundational issues (such as racial inequities, police culture, and police unions), data and reporting, training, policies, technology, and consequences for officers. Reviewing the priority research topics in each focus area, similar themes emerged, especially around the need for more-extensive and more-systematic data collection and around the use of agency policies to better govern a range of operations related to police violence, such as data collection and reporting and technology.
