Obama accepted his Peace Prize today and mounted a defense of war as a tool for peace.  But activists Robi Damelin, who lost her son to a Palestinian sniper, and Mazen Faraj, who lost his father to an Israeli sniper, are advocating a different approach. Members of The Parents Circle-Families Forum, they're touring the U.S. with Cartoons in Conflict, an exhibit featuring the work of forty renowned American and international cartoonists, who offer their singular perspective on conflict, reconciliation, and peace. For International Human Rights Day, Robi and Mazen join Laura in the studio to tell their stories, how they came to work for peace, and talk about the cartoons they're presenting.
