Joseph Blocher, the Lanty L. Smith ’67 Professor of Law at Duke Law and faculty co-director of the Duke Center for Firearms Law, discusses his recent two scholarly articles: "Why Regulate Guns?" and "When Guns Threaten the Public Sphere: A New Account of Public Safety Regulation Under Heller." Prof. Blocher co-wrote both pieces with Reva Siegel, the Nicholas deB. Katzenbach Professor of Law at Yale Law School.
