It's hard to imagine finding common ground on the problem of gun violence. In the 1990s, Dr. Mark Rosenberg and former Congressman Jay Dickey (R-AR) were "arch enemies." But over time, the "curly-haired, liberal, Jewish kid" and the "lifelong NRA member" became good friends. Science helped them bridge the gap, and together they proposed a way forward: a way to balance gun safety... and gun rights. Guest: Dr. Mark Rosenberg, President and CEO of the Task Force for Global Health, and the founding director of the National Center for Injury and Prevention Control at the Centers for Disease Control and Prevention.
