The 9/11 Commission releases a new report on how the 9/11 plot developed. Most of their information appears to come from interrogations of prisoners Khalid Shaikh Mohammed (KSM), the 9/11 mastermind, and Ramzi bin al-Shibh, a key member of the al-Qaeda Hamburg cell. In this account, the idea for the attacks appears to have originated with KSM. In mid-1996, he met bin Laden and al-Qaeda leader Mohammed Atef in Afghanistan. He presented several ideas for attacking the US, including a version of the 9/11 plot using ten planes (presumably an update of Operation Bojinka’s second phase plot (see February-Early May 1995)). Bin Laden does not commit himself. In 1999, bin Laden approves a scaled-back version of the idea, and provides four operatives to carry it out: Nawaf Alhazmi, Khalid Almihdhar, Khallad bin Attash, and Abu Bara al Taizi. Attash and al Taizi drop out when they fail to get US visas. Alhazmi and Almihdhar prove to be incompetent pilots, but the recruitment of Mohamed Atta and the others in the Hamburg al-Qaeda cell solves that problem. Bin Laden wants the attacks to take place between May and July 2001, but the attacks are ultimately delayed until September. [9/11 Commission, 6/16/2004] However, information such as these accounts resulting from prisoner interrogations is seriously doubted by some experts, because it appears they only began cooperating after being coerced or tortured. For instance, it is said that KSM was “waterboarded,” a technique in which his head is pushed under water until he nearly drowns. Information gained under such duress often is unreliable. Additionally, there is a serious risk that the prisoners might try to intentionally deceive. [New York Times, 6/17/2004] For instance, one CIA report of his interrogations is called, “Khalid Shaikh Mohammed’s Threat Reporting—Precious Truths, Surrounded by a Bodyguard of Lies.” [Los Angeles Times, 6/23/2004] The Commission itself expresses worry that KSM could be trying to exaggerate the role of bin Laden in the plot to boost bin Laden’s reputation in the Muslim world. [9/11 Commission, 6/16/2004] Most of what these prisoners have said is uncorroborated from other sources. [New York Times, 6/17/2004] In 2007, it will be alleged that as much as 90 percent of KSM’s interrogation could be inaccurate, and that he has recanted some of his confessions (see August 6, 2007).
