A recent conference by the Rock Ethics Institute at Penn State brought researchers into the Ethics of Policing to State College.
Franklin Zimring, from the University of California, Berkley, studies police use of lethal force in the United States. Vesla Weaver from Johns Hopkins University studies how contact with the criminal justice system affects political engagement. Michael Walzer from the Institute for Advanced Study studies the differences between police and soldiers.
Police kill about 1,000 Americans every year. We talked with Zimring, Weaver and Walzer about the status of policing in the United States and how it got to be how it is today.
