Maj. Gen. Antonio Taguba is blaming the scandal on "failure in leadership from the briagde commander on down, lack of discipline, no training whatsoever, and no supervision". Apparently soldiers need to be specifically trained not to undress prisoners, tie them to leashes and then photograph them. What exactly the military's guidelines are for torturing prisoners, I have no idea, but the Times story contains these rather confusing paragraphs back to back:
Before the Senate panel, General Taguba testified that in his investigation, he never found any evidence that the abusive techniques were part of military policy.
"I think it was a matter of soldiers with their interaction with military intelligence personnel who they perceived or thought to be competent authority," the general said. Some guards have said they had been asked by intelligence officers to rough up the prisoners to help along the interrogations. General Taguba said the guards "were probably influenced by others but not necessarily directed by others."
