I remember when the second batch of Torture Fotos were first rumored to exist (about '04?); that they were too graphic and inflammatory to release to the public. We may speculate that they were not released because they weren't already on the net. So "more than 400 individuals were disciplined" (mostly enlisted men and sergeants, I'm sure), but I'd further bet that none of those disciplined were CIA agents known to have been present.
Why did those knuckleheads photograph themselves, unless they had been totally assured that their conduct was approved by the wraiths, and why do the spinners suppose the public is just as stupid and gullible as the hillbilly guards, just because we are.
