This is one of those things that seems so obvious, but I have never heard it mentioned in my time in Korea (though there seems to be a considerable amount a work being done my the Truth and Reconciliation Committee). Regardless of where the war is, people are killed, both civilian and military. War movies are made on the callous actions of a few (or a even a policy) in laying judgment on their captives.
I really do hope that Korea acknowledges this and works to give a voice to the victims and their families. As is too often the case, people not directly affected just want the nastiness to go away and not interfere with their righteous few of their history and brethren. I hope this is one of those times where this urge is overcome.
