Sept. 11 Plotter Cooperated After Waterboarding
After enduring the CIA's harshest interrogation methods and spending more than a year in the agency's secret prisons, Khalid Sheik Mohammed stood before U.S. intelligence officers in a makeshift lecture hall, leading what they called "terrorist tutorials."
Speaking in English, Mohammed "seemed to relish the opportunity, sometimes for hours on end, to discuss the inner workings of al-Qaeda and the group's plans, ideology and operatives," said one of two sources who described the sessions, speaking on the condition of anonymity because much information about detainee confinement remains classified. "He'd even use a chalkboard at times."
