A confidential report to Army generals in Iraq in December 2003 warned that members of an elite military and CIA task force were abusing detainees, a finding delivered more than a month before Army investigators received the photographs from Abu Ghraib prison that touched off investigations into prisoner mistreatment.

It also said coalition fighters could be feeding the Iraqi insurgency by "making gratuitous enemies" as they conducted sweeps netting hundreds of detainees who probably did not belong in prison and holding them for months at a time.
