Muslim American Society: "Davis, 27, admitted to stomping on the fingers and toes of a group of seven bound and hooded inmates during an episode of late-night abuse in November 2003. Other guards then undressed the prisoners and stacked them into a naked human pyramid, the news agency reports."

...

"Davis argues he and other guards roughed up prisoners at the behest of intelligence officials who wanted to extract information from the prisoners, reports Reuters.

'Basically, when the intelligence personnel, when they bring them down there, anyone that comes in there with intelligence value, they want to interrogate them and they would ask you to loosen them up,' Davis told ABC News last year."
