Soufan also laments what might have been learned from Khalid Sheik Mohammed if had been questioned by knowledgable agents instead of CIA psychologists:
Some of the information that is cited in the memos — the revelation that Mr. Mohammed had been the mastermind of 9/11, for example, and the uncovering of Jose Padilla, the so-called dirty bomber — was gained from another terrorism suspect, Abu Zubaydah, by “informed interrogation,” conducted by an F.B.I. colleague and me. The arrest of Walid bin Attash, one of Osama bin Laden’s most trusted messengers, which was also cited in the 2005 C.I.A. memo, was thanks to a quick-witted foreign law enforcement officer, and had nothing to do with harsh interrogation of anyone. The examples go on and on.A third top suspected terrorist who was subjected to enhanced interrogation, in 2002, was Abd al-Rahim al-Nashiri, the man charged with plotting the 2000 bombing of the Navy destroyer Cole. I was the lead agent on a team that worked with the Yemenis to thwart a series of plots by Mr. Nashiri’s operatives in the Arabian Peninsula — including planned attacks on Western embassies. In 2004, we helped prosecute 15 of these operatives in a Yemeni court. Not a single piece of evidence that helped us apprehend or convict them came from Mr. Nashiri.
Mr. Mohammed knew the location of most, if not all, of the members of Al Qaeda’s leadership council, and possibly of every covert cell around the world. One can only imagine who else we could have captured, or what attacks we might have disrupted, if Mr. Mohammed had been questioned by the experts who knew the most about him.
