• Stress positions: The interrogator would have Zubaydah either sit on the floor with his legs extended in front of him and his arms raised over his head, or kneel on the floor while leaning back at a 45-degree angle. Again, the intent would be to cause discomfort or fatigue.
• Sleep deprivation: Zubaydah would be made to stay awake for up to 11 days at a time.
• Waterboarding: The interrogator would strap Zubaydah to an inclined bench, with his feet slightly elevated. A cloth would be placed over his forehead and eyes, and water would be applied to the cloth in a controlled manner—for 20 to 40 seconds from a height of 12 to 24 inches. The intention would be simulate the sensation of drowning.
• There was also another technique that I’m barred from describing that was so gruesome that the Justice Department later stopped short of approving it.
