I'll bet a pretty good percentage of "the rest" were NOT looting and raping, but doing what most of us would do in that situation. The looters and the rapers were most likely a minority -- but like garlic, a little bit of them go a long, long way. Really, there's no call to er ... whitewash ... (for lack of a more apropriate term?) all "the brothers" for the acts of some monsters.
Then why didn't they act like men and take care of the situation? They should have hung the criminals on their own.
