“This elegant generalization is mathematically very appealing; but physics means facing facts. You should take up case by case.”

Context: We did not learn Abu Ahmed’s real name or alias as a result of waterboarding or any "enhanced interrogation technique" used on a detainee in U. S. custody. None of the three detainees who were waterboarded provided Abu Ahmed’s real name, his whereabouts, or an accurate description of his role in Al-Qaeda. … In fact, not only did the use of "enhanced interrogation techniques" on Khalid Sheikh Mohammed not provide us with key leads on bin Laden’s courier, Abu Ahmed; it actually produced false and misleading information. Khalid Sheikh Mohammed specifically told his interrogators that Abu Ahmed had moved to Peshawar, got married, and ceased his role as an Al-Qaeda facilitator — which was not true, as we now know. … It was not torture or cruel, inhuman, and degrading treatment of detainees that got us the major leads that ultimately enabled our intelligence community to find Osama bin Laden. … we are again engaged in this important debate, with much at stake for America’s security and reputation. Each side should make its own case, but do so without making up its own facts.
