Held in a secret CIA prison in Thailand, al-Qaeda leader Abu Zubaida is interrogated by a new team of CIA interrogators led by James Elmer Mitchell and Dr. R. Scott Shumate. Mitchell is a psychologist contracted to the CIA, while Shumate is the chief operational psychologist for the CIA’s Counterterrorist Center. Mitchell wants to use torture techniques based on reverse-engineering SERE (Survival, Evasion, Resistance, Escape), a class he has taught that trains US soldiers to resist torture by the enemy. But the techniques have never been tried before and studies will later determine they are not effective in obtaining good intelligence (see Mid-April 2002). Zubaida is resistant to Mitchell’s new aggressive techniques and refuses to talk. Mitchell concludes Zubaida will only talk when he has been rendered completely helpless and dependent, so the CIA begins building a coffin to bury Zubaida alive in but not actually kill him. This creates an intense controversy over the legality of such a technique, and ultimately it appears the burying alive is never carried out. Both domestic and international law clearly prohibits death threats and simulated killings. However, a number of aggressive techniques have just been approved at the highest political level (see Mid-March 2002), so opponents to these techniques are mostly powerless. Shumate is so strongly opposed to these techniques that he leaves in disgust. He will later tell his associates that it was a mistake for the CIA to hire Mitchell. But with Shumate gone, Mitchell is now free to use more extreme methods, and the torture of Zubaida begins in earnest around the middle of May. [Vanity Fair, 7/17/2007] Around this time, the FBI also washes its hands of the controversial techniques and withdraws its personnel from the secret prison (see Mid-April-May 2002).
