The Washington Post has an interesting article supporting the contention that harsh interrogation techniques such as sleep deprivation and waterboarding resulted in valuable intelligence from 9/11 attack planner Khalid Sheikh Mohammed: How a Detainee Became An Asset.

These scenes provide previously unpublicized details about the transformation of the man known to U.S. officials as KSM from an avowed and truculent enemy of the United States into what the CIA called its “preeminent source” on al-Qaeda. This reversal occurred after Mohammed was subjected to simulated drowning and prolonged sleep deprivation, among other harsh interrogation techniques.

“KSM, an accomplished resistor, provided only a few intelligence reports prior to the use of the waterboard, and analysis of that information revealed that much of it was outdated, inaccurate or incomplete,” according to newly unclassified portions of a 2004 report by the CIA’s then-inspector general released Monday by the Justice Department.
