I think that isn't without warrant either. Since day one of OEF/OIF/Whatever the hell we're doing in Libya is called/Our little Syria adventure/etc. NSW and SOCOM as a whole have been at the absolute forefront with more of their time spent in the tall grass than at home. It's why they have had retention problems over the last two or three years. It's also colored the way they look at the world. Those guys have seen some real shit and lived around it for years. We select NSW operators to have a killer edge, train and hone that edge, deploy them for years on end in high intensity conflict, and then expect them to act like saints. Having these dudes under constant exposure to warfare has undoubtedly shifted their moral compasses in the same manner that many of our boys who came back from the trenches of WWI had theirs shifted.
Is it justification for what they may have done? No. But the moral outrage many are experiencing over this doesn't seem justified either. We're in the middle of a war and we expect these guys to be stone cold killers and ruthless on the battlefield. Don't be surprised when they do ruthless, cold blooded things.
