50 Days of Sleep Deprivation

Guantanamo records show that Salim Hamdan was subjected to sleep deprivation for 50 days (see also here).

After 72 hours of sleep deprivation, people start to hallucinate. They literally become psychotic and desperate.

It's a great technique to get false confessions, because you tell them what they want, and they are inclined to give it to you, but to get accurate information, not really, because after a few days, much less 50 days (!), they no longer have a grasp on reality.

There are a few thousand people, both in the active duty military and in government civilian service, who need to spend the rest of their lives in jail over this.
