Where have we gone wrong in our approach to policing? With seemingly every new incident of police and civilian conflict gone-awry captured on cell phone cameras, many Americans are just now realizing law enforcement is not applied equally. Professor Barry Friedman is the founding director of NYU Law’s Policing Project and is one of the country’s leading authorities on constitutional law, policing, criminal procedure, and the federal courts. Professor Friedman joins Dave Ross in-studio for an insightful review of the state of policing in our country. His new book is titled, "Unwarranted: Policing Without Permission."
