Christian Richter’s work brings him into contact with some of humanity’s worst outrages. As head of the United Nations investigative team to promote accountability for the crimes committed by ISIL in Iraq, he seeks justice for victims of the notoriously violent terror group.  “Justice gives relief not only to the victims, but to a prosecutor as well. That is what keeps you upright and keeps you going on and says it is meaningful what you're doing.” Islamic State, or ISIL, stands accused of war crimes, crimes against humanity and genocide. Iraq’s Yazidi community were among those worst hit, with thousands killed or enslaved by the group. In this episode, Christian Richter reflects on the impact on survivors, the difficulty of gathering testimony and on keeping faith in humanity when faced with its darkest acts. “When you're an investigator, you'll see pretty clearly that ISIL did not hesitate at all to commit these crimes, while terrorizing the population and trying to establish their own caliphate or regime.”
