In this Aug. 21, 2013, photo, Michael Donald Kirby, center, the chairman of the U.N. commission of Inquiry on human rights in North Korea, listens to Ahn Myung-chul, right, who worked as a guard and driver at several political prisoner camps in the 1990s before defecting to south, during the U.N. hearing in Seoul, South Korea. Testimony by North Korean defectors at U.N. hearings this week in Seoul has produced chilling testimony of systematic rape, murder and torture - but it’s also a poignant reminder of past, toothless U.N. efforts to get Pyongyang to better treat its citizens.
