I asked CIA Director Leon Panetta for the facts, and he told me the following: The trail to bin Laden did not begin with a disclosure from Khalid Sheik Mohammed, who was waterboarded 183 times. The first mention of Abu Ahmed al-Kuwaiti — the nickname of the al-Qaeda courier who ultimately led us to bin Laden — as well as a description of him as an important member of al-Qaeda, came from a detainee held in another country, who we believe was not tortured. 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, the use of “enhanced interrogation techniques” on Khalid Sheik Mohammed produced false and misleading information. He specifically told his interrogators that Abu Ahmed had moved to Peshawar, got married and ceased his role as an al-Qaeda facilitator — none of which was true. According to the staff of the Senate intelligence committee, the best intelligence gained from a CIA detainee — information describing Abu Ahmed al-Kuwaiti’s real role in al-Qaeda and his true relationship to bin Laden — was obtained through standard, noncoercive means.
I know from personal experience that the abuse of prisoners sometimes produces good intelligence but often produces bad intelligence because under torture a person will say anything he thinks his captors want to hear — true or false — if he believes it will relieve his suffering. Often, information provided to stop the torture is deliberately misleading.
Mistreatment of enemy prisoners endangers our own troops, who might someday be held captive. While some enemies, and al-Qaeda surely, will never be bound by the principle of reciprocity, we should have concern for those Americans captured by more conventional enemies, if not in this war then in the next.
