Law Professor, Shima Baradaran Baughman, joins us to discuss the current system of gathering key statistics on the performance of law enforcement. We discuss the limitations, errors, and incompleteness of the current data model, and discuss possible solutions. We focus on her article entitled HOW EFFECTIVE ARE POLICE? THE PROBLEM OF CLEARANCE RATES AND CRIMINAL ACCOUNTABILITY. This is part 2 in our Use of Force Registry series, but this is where things take a change in a new direction, a new way of thinking on police reform.
