Well .. you may be right about that .. but since sexual crimes are not spoken of .. a lot of these people who may have known or witnessed anything, may not be willing to speak up for fear of ending up the same way.
In this case I would think the opposite would be true. It would be their way of screaming for more bloody Jihad against our soldiers. You know, the infidel oppressive murdering Americans are raping all our women and little girls.
I don't know about Iraq, but in Afghanistan and Pakistan, sometimes gang-rape is a punishment for women for a variety of alleged offense. Irony.
