Do you think she would have been demoted and discharged if they'd testified she was responding to an attack?
Hell, man -- even she doesn't deny it. The best she can do is say, "mistakes will be made," and appeal to our sympathy by pointing out the dangers (which are the same as those faced by the guards who don't beat their prisoners, BTW).
C'mon, now, C-man. It's not "pro-Iraqi" to agree that Americans should not beat prisoners, in the same way that it's not "pro-criminal" to argue that American cops shouldn't beat prisoners.
If the prisoners attacked them first, then they deserve whatever beating they got. But if the guards beat their prisoners for no good reason, then the cops deserve punishment.
