"Guilty of what? taking a crap on a dead jihadi getting a little head from an employee during working hours, cutting off a finger lying to the whole nation about it? Big Deal!
There may be a lot of cultures spread out throughout the world where the mutilation and desecration of the body of a dead enemy is acceptable under certain circumstances, or maybe even commonplace, or where honor killings may be the norm rather than the rule. That's not the case in this culture, and the sort of actions that you consider "no big deal", run completely against the grain of society.
It's not OK.
I'm not saying that these soldiers did anything, they stood trial and were acquited, but the line of thinking that would excuse off similar behavior is unacceptable.
