At Salon, Mark Benjamin reviews a cache of internal CIA documents giving directions on how to waterboard prisoners:

Interrogators pumped detainees full of so much water that the CIA turned to a special saline solution to minimize the risk of death, the documents show. The agency used a gurney “specially designed” to tilt backwards at a perfect angle to maximize the water entering the prisoner’s nose and mouth, intensifying the sense of choking – and to be lifted upright quickly in the event that a prisoner stopped breathing.

The documents also lay out, in chilling detail, exactly what should occur in each two-hour waterboarding “session.” Interrogators were instructed to start pouring water right after a detainee exhaled, to ensure he inhaled water, not air, in his next breath. They could use their hands to “dam the runoff” and prevent water from spilling out of a detainee’s mouth. They were allowed six separate 40-second “applications” of liquid in each two-hour session – and could dump water over a detainee’s nose and mouth for a total of 12 minutes a day. Finally, to keep detainees alive even if they inhaled their own vomit during a session – a not-uncommon side effect of waterboarding – the prisoners were kept on a liquid diet. The agency recommended Ensure Plus.

Once more we see that Ensure Plus, a staple of the force-feeding regime used at Guantánamo, also regularly featured as a part of the torture regime for CIA prisoners.

While these memos show senior lawyers at the Justice Department providing a “how to” manual for waterboarding and other techniques, explaining exactly how to torture without risk of criminal prosecution, the involvement of medical professionals is still more chilling. Including this:

The memo also contains a last, little-noticed paragraph that may be the most disturbing of all. It seems to say that the detainees subjected to waterboarding were also guinea pigs. The language is eerily reminiscent of the very reasons the Nuremberg Code was written in the first place. That paragraph reads as follows:

“NOTE: In order to best inform future medical judgments and recommendations, it is important that every application of the waterboard be thoroughly documented: how long each application (and the entire procedure) lasted, how much water was used in the process (realizing that much splashes off), how exactly the water was applied, if a seal was achieved, if the naso- or oropharynx was filled, what sort of volume was expelled, how long was the break between applications, and how the subject looked between each treatment.”

While the identities of the lawyers involved in introducing the torture program has become public, the doctors involved have largely retained their anonymity. Why?
