Filmmaker Martin Doblmeier discusses "The Power of Forgiveness," his new documentary for PBS. The film tells stories of both individual and group forgiveness, and reports on forgiveness studies, a blossoming field of scientific inquiry. Doblmeier talks about his trip to still-segregated Northern Ireland, where experts are trying to integrate the lessons of forgiveness into the curriculum, and recounts the heated reaction to the proposal to build a "garden of forgiveness" at the Ground Zero memorial in New York City.
