Osama bin Laden Responsible for the 9/11 Attacks?

Kean and Hamilton, however, reported that they had no success in "obtaining access to star witnesses in custody . . . , most notably Khalid Sheikh Mohammed."19 Besides not being allowed to interview these witnesses, Commission members were not even permitted to observe the interrogations through one-way glass or to talk to the interrogators.20 Therefore, Kean and Hamilton complained: "We . . . had no way of evaluating the credibility of detainee information. How could we tell if someone such as Khalid Sheikh Mohammed . . . was telling us the truth?"21

An NBC "deep background" report in 2008 pointed out an additional problem: KSM and the other al-Qaeda leaders had been subjected to "enhanced interrogation techniques," i.e., torture, and it is now widely acknowledged that statements elicited by torture lack credibility. "At least four of the operatives whose interrogation figured in the 9/11 Commission Report," NBC pointed out, "have claimed that they told interrogators critical information as a way to stop being ‘tortured.'" NBC then quoted Michael Ratner, president of the Center for Constitutional Rights, as saying: "Most people look at the 9/11 Commission Report as a trusted historical document. If their conclusions were supported by information gained from torture, . . . their conclusions are suspect."22
