Ben Ferencz should be a household name. That idea is effectively and energetically argued in the documentary "Prosecuting Evil," directed by Barry Avrich. 98-year-old lawyer Ferencz is the last surviving prosecutor of the Nuremberg Trials, and an icon of international criminal justice. At 27, he prosecuted and won his first case – the biggest murder trial of the 20th century (and hopefully, ever), against 24 members of the notorious Nazi death squads known as the Einsatzgruppen. The determined and fiery Ferencz still works every day fighting for peace, the very manifestation of what we might call "The Greatest Generation."
