The Abuse Continues?

We have more evidence of serious detainee abuse at Guantanamo Bay:

In a sworn affidavit filed with the Pentagon Inspector General, Sgt. Cerveny says she met several Navy prison guards at a club on the base where, over drinks, they described harsh physical abuse.
"One sailor specifically said, 'I took the detainee by the head and smashed his head into the cell door,'" Sgt. Cerveny tells ABC News in an exclusive interview.

She says she was "shocked" to hear several guards from different parts of the camp speak openly of mistreating prisoners. "Everyone in the group laughed at all their stories of beating detainees," she recalled. "None of them looked like they cared. None of them looked shocked by it."

One of the guards "was telling his buddy, 'Yeah, this one detainee, you know, really pissed me off, irritated me.  So I just, you know, punched him in the face.'"

I wonder why they didn't feel shocked. Gitmo is heavily monitored and staffed by professionals. It's certainly more closely monitored than many other detention centers. It couldn't be because abuse and torture are still Bush administration policy, could it?
