$hit like this happen at every war, and at every conflict. Frankly, I'm surprised it doesn't happen more - American soldiers are out there, facing a very foreign and extremely hostile enemy, and that's very demanding and stressing. So, yeah... they made a guy stand a box, threatning that if he stepped down, he'd be electrecouted. That's not very nice... but how about, say, going into a village, and decapitating every single human there, and then hanging their headless bodies in the village square? What would you say to that? The fact remains, the USA has NEVER done such a thing (Not in recent history, anyway), while others have, and trying to find anacdotes like these... well, that's cute, but hardly a definitive image of what the American army is like.

These twisted freaks will be trialed and punished, and I'm pretty sure none of their friends will ever talk to them again.
