The world said "Never Again!" after the Holocaust and yet FRONTLINE asks why the genocide in Darfur was allowed. Meticulously chronicled, endlessly debated at the UN, and allowed to proceed unabated for years, more than 200,000 killed and 2.5 million driven from their homes. As governments failed to act, private citizens and celebrities protest the carnage. PBS (2007), English, DVDRun Time: 60 minutes.
