Here's a key graf from the story:
"Indeed, the single most iconic image to come out of the abuse scandal--that of a hooded man standing naked on a box, arms outspread, with wires dangling from his fingers, toes and penis--may do a lot to undercut the administration's case that this was the work of a few criminal MPs. That's because the practice shown in that photo is an arcane torture method known only to veterans of the interrogation trade. "Was that something that [an MP] dreamed up by herself? Think again," says Darius Rejali, an expert on the use of torture by democracies. "That's a standard torture. It's called 'the Vietnam.' But it's not common knowledge. Ordinary American soldiers did this, but someone taught them."
Who might have taught them? Almost certainly it was their superiors up the line. Some of the images from Abu Ghraib, like those of naked prisoners terrified by attack dogs or humiliated before grinning female guards, actually portray "stress and duress" techniques officially approved at the highest levels of the government for use against terrorist suspects."
