Last weekend’s massacre in Tucson, Arizona, at a “Congress On Your Corner” event by Rep. Gabrielle Giffords (D-AZ) has sparked waves of rhetoric and policy debates, especially regarding gun laws. On today’s Radio Times, Marty will explore Arizona’s gun laws and whether the shootings will change policies and politics surrounding access to guns. Our guests are DAVID KOPEL, research director at the Independence Institute and an adjunct professor of law at the University of Denver; and JOHN J. DONOHUE III, a Stanford Law professor who has conducted extensive research into gun laws.
