In this June 9, 2010, photo, Yang Won-jin, whose father was believed summarily executed and dumped into a mass grave 60 years ago, talks during an interview with The Associated Press in Seoul, South Korea. Shutting down its inquiry into South Korea's hidden history, a century of human rights abuses, Seoul's Truth and Reconciliation Commission will leave unexplored scores of suspected mass graves believed to hold remains of tens of thousands of South Korean political detainees executed by their government early in the 1950-53 war, sometimes as U.S. officers watched. In a political about-face, the commission, also investigating the U.S. military's large-scale killing of Korean War refugees, has ruled the Americans in case after case acted out of military necessity.
