I think what's lost here is that he entered a guilty plea. We all know that judicial systems dole out softer, for lack of a better word, punishment when someone admits there guilt. That said, shooting people who are blind folded and bound is not how any member of the US military is trained. Every soldier, sailor, marine, and airmen is taught the Geneva Covention and the Law of Armed Conflict. I can understand where they were coming form but that by no means gives them the right to summarily execute prisoners. If we do that, then we have failed, not simply militarily, but socially. Killing of prisoners is a line that we simply should not cross, it means that we are no better than they are.
Good post.
