What went on at Guantanamo?

I was listening to my local Pacifica station this morning, they had a segment with Janis Karpinski, the Brig. General on whom Abu Ghraib was pinned. One of the things she said is that Maj. Gen. Geoffrey Miller, the guy who was in charge of Guantanamo and was later brought into Abu Ghraib, was a field artillery officer with no background in prisoner handling and interrogation before Rumsfeld placed him at Guantanamo.

Is it any wonder, then, that stuff like this was going on?

WASHINGTON - Military interrogators posing as FBI agents at the U.S. detention center at Guantanamo Bay, Cuba, wrapped terrorism suspects in an Israeli flag and forced them to watch homosexual pornography under strobe lights during interrogation sessions that lasted as long as 18 hours, according to one of a batch of FBI memos released Thursday.....

Maj. Gen. Geoffrey Miller, who was in charge of the prison at the time, overrode the FBI agents' protests, according to the documents.

The memos offer some of the clearest proof yet that the abuses and torture of prisoners in U.S. military custody weren't the isolated actions of low-ranking soldiers but a result of policies approved by senior officials, the ACLU said.

I'm not an expert, but, on top of everything else, military interrogators posing as FBI agents?
