Dr. Rashawn Ray is a David M. Rubenstein fellow in Governance Studies at the Brookings Institution. He's also an associate professor of sociology at the University of Maryland, College Park, where he directs the Lab for Applied Social Science Research (LASSR). He is a scholar of, among other things, police-civilian relations and has done a lot of work on police-involved killings. He joined Benjamin Wittes to discuss the mechanisms of police violence, what causes it, what can be done to address it and reduce it, and the role of race in this problem. They talked about police unions, implicit bias, the difference between legality and morality in police shootings and what policy levers are available to bring an end to the rash of police killings.
