"The South Koreans had been trying for years to have this incident, and others, recognized. They had brought petitions to the U.S. government, and in the mid-'90s, the U.S. government gave them a response, which said that it didn't happen and that U.S. troops were not in the region. Around that time a South Korean AP reporter heard about this and began working on it. And in the United States we began working on it as well. We interviewed more than 130 veterans. We spent weeks and weeks and weeks at the National Archives. And in the end, we were able to document this with interviews from GIs who were there, with survivors of this incident in South Korea who were there, and although there wasn't, we didn't find the document that points to this particular incident, we did find many documents describing such instances across the warfront. And this past week, my colleague Charlie Hanley and I reported on the letter from the U.S. Ambassador to Seoul informing the State Department that American soldiers would shoot refugees approaching their lines. And this letter, that we just reported last week, is the strongest indication yet that such a policy existed for all U.S. forces in Korea. And it's the first evidence that that policy was known to upper ranks of the U.S. government."
