There seems to be no shortage of people rationalizing this behavior and relieved to have an explanation, implying it could be condoned.
Just like the all too common abuse of power by police, the end never justifies the means and can never be condoned. Those with power have a much higher responsibility, not less with justifications like "that's just how war is".
I don't think anyone is condoning this behavior (certainly not the soldier in the interview). However, I should mention that police abusing power is a little different, since they aren't in a WAR ZONE, having been shot at minutes before. Whether or not the soldiers erred (and they did) is not the question here. The question is, why did WikiLeaks present it in the way they did?
People are attacking WikiLeaks because they feel betrayed by the organization. I know I do. What was supposed to be an impartial mediator of classified data turned out to be a sensationalist mediator of classified data presented with a spin that would make Fox News proud.
In closing: Wikileaks exposed us to civilian murder. This would normally by fine. However, they also distorted the facts and the context of the event to support a sensationalist publicity routine. That is the problem here.
I'm not sure why you say that. I didn't think "war was cut and dry" prior to this video being released. Did you?
