Tracey L. Meares discusses her article, “The Good Cop: Knowing the Difference Between Lawful or Effective Policing and Rightful Policing — And Why it Matters.” Prof. Meares describes the two traditional roles of policing as they function under the law and in fighting crime. These two roles place the responsibility of policing on the behavior of citizens. But Prof. Meares suggests a third role, rightful policing, that places the emphasis on procedure, fairness, and transparency of conduct of the police while interacting with the public. Tracey L. Meares is the Walton Hale Hamilton Professor and a Founding Director of the Justice Collaboratory at Yale Law School.
