It's not simply anecdotal about me and my conduct. It's a firm knowledge of the U.S. military's internal policies and controls.
As for that video -- I wasn't sure it's one that I had seen, so I watched it again. I don't know what point you're trying to make -- those men were completely legitimate targets. I would have killed them myself. I'm sorry you had to confront what war's actually like, but killing is sort of the whole point.
