HARDtalk - Efraim Zuroff, Director of the Simon Wiesenthal Centre, Israel

The world's last Nazi hunter, Efraim Zuroff, has spent the past thirty years tracking down suspected Nazi war criminals to try to bring them to justice. Most are elderly, approaching the end of their lives. He tells Zeinab Badawi that the passage of time doesn't diminish guilt and his determination to hold Nazis accountable for the crimes they committed is not waning.
