The secret overseas black sites" where the CIA conducted the interrogations are empty now, if not already dismantled. They were never examined by a congressional committee, nor inspected by the international Red Cross. The black sites not only imprisoned men but reduced them to a near helpless state. The aim, as outlined in one document, was to teach every detainee "to perceive and value his personal welfare, comfort and immediate needs more than the information he is protecting." The prisoners' arrival -- almost always in diapers -- was engineered to achieve that end. After being shaved, stripped and photographed nude, detainees were examined by CIA medical and psychological personnel. Then came a preliminary interrogation that would determine the prisoners' fate. Only those considered extremely cooperative would avoid a trio of techniques designed to produce a "baseline, dependent" state: the deprivation of clothes, solid food and sleep. Follow-up sessions would start with the prisoner standing with his back against a wall and a towel or collar to prevent whiplash wrapped around his neck. He could be thrown against the wall just once "to make a point, or 20 to 30 times consecutively." Prisoners so abhorred the repeated slamming that they would remain in so-called stress positions, such as painful kneeling postures, for hours to avoid a return to the wall, according to one Dec. 30, 2004, memo that amounts to a CIA blueprint for breaking a detainee's will. Earlier this year, the Obama administration released a series of Justice Department memos laying out legal rationales for the array of coercive interrogation methods the CIA employed.
