"The people in that prison had ALL tried to kill U.S. Soldiers and Iraqi civilians" (two bears)

Further to my comment to the effect that this claim just is not true -this is what General Taguba had to say in his official report. Here's a relevant quote from Seymour Hersh in the New Yorker TORTURE AT ABU GHRAIB:

"A lack of proper screening also meant that many innocent Iraqis were wrongly being detained—indefinitely, it seemed, in some cases. The Taguba study noted that more than sixty per cent of the civilian inmates at Abu Ghraib were deemed not to be a threat to society, which should have enabled them to be released. Karpinski's defense, Taguba said, was that her superior officers "routinely" rejected her recommendations regarding the release of such prisoners.

The New Yorker coverage of this is the one from which most of the rest of the media stories appear to take their starting point.
