Daniel Richman and Sarah Seo are professors at Columbia Law School, and they are co-authors of a recent article on Lawfare entitled, "Toward a New Era for Federal and State Oversight of Local Police." Benjamin Wittes sat down with them to discuss the article, the history of the federal-state relationship in law enforcement, how the feds came to play an oversight role with respect to police departments, the limits of that role inherent in the cooperative relationship that law enforcement agencies engage in for other reasons, the role that the feds might play under new legislation and the role that state governments may play as well. Sign up for Lawfare's Patreon to support our podcast and get access to its ad-free feed and other perks.
