I’ve interviewed guards at Guantanamo and heard their frustrations, to the point where I was kind of shocked there weren’t more severe beatings at the hands of 19 year olds who have cocktails of excrement thrown at them. Obviously I’m not excusing any such beatings; I’m just saying that when someone is given responsibility over other people in an environment of legal impunity, standards of acceptable behavior can slip very fast. That’s just human nature.
