Here's some more stuff that was reported in this Washington Post article (I wonder if they will have to retract it?):
About a dozen of the FBI interviews included allegations that guards or interrogators at Guantanamo Bay either mishandled the Koran to outrage prisoners or engaged in religiously offensive behavior that included, in one instance, throwing a prisoner's prayer cap in the trash.
The records also include numerous allegations that guards or interrogators at Guantanamo Bay used sexually suggestive techniques designed to humiliate Muslim men. One said he was forced to stand naked in front of a female interrogator. Another said he was "touched sexually" by male guards.
The government has said two female interrogators at Guantanamo Bay have been reprimanded for sexually related techniques, including one for smearing ink on a detainee and telling him that it was menstrual blood.
The FBI records also include at least 19 separate allegations of beatings or other severe violence on the part of guards or others in control of the prisoners in Afghanistan or at Guantanamo Bay. One captive said he was kicked in the stomach, back and head by U.S. military personnel at an unknown location and suffered a broken shoulder.
"The evidence that there was systemic and widespread abuse of detainees in U.S. custody continues to mount and the government continues to turn a blind eye to this evidence," said Amrit Singh, an ACLU lawyer.
