Lauren Gunderson, the most produced playwright in America, is launching a nationwide campaign of theater activism against gun violence with her new play, "Natural Shocks." She is waiving royalties to the piece, so that communities across the country can put on readings the weekend of April 20th -- the 19th anniversary of the Columbine school massacre. Gunderson joins Forum to discuss her commitment to ending gun violence and how theater can be used as a means of social change.
