Mohammed al-Qahtani

Mohammed al-Qahtani (1979?-) is alleged to be the "20th hijacker" who would have participated in the 9-11 attack, and is a prisoner at Guantanamo detention camp. Captured by Pakistani forces near the Afghanistan border with Pakistan in December 2001, his legal status is evolving; U.S. filings about his detention cite:
 * He was a member of al-Qaeda, having personally sworn the bayat oath to Osama bin Laden,
 * Received weapons training
 * Agreed to conduct a martyrdom operation in the U.S. but was turned away by immigration authorities in August 2004
 * Was with bin Laden at the Battle of Tora Bora

He denied, which is suggested by the summary of evidence, that he had specific prior knowledge of the 9-11 attack. According to an interrogation log acquired by Time magazine and confirmed by the Department of Defense, "On Jan. 10, 2003, al-Qahtani says he knows nothing of terrorists but volunteers to return to the gulf states and act as a double agent for the U.S. in exchange for his freedom". After harsher interrogation measures were authorized by Secretary of Defense Donald Rumsfeld, he gave more specifics about al-Qaida, but it is not clear if he gave that due to the increased intensity, or it was through We Know All interrogation techniques based on information obtained from Khalid Sheikh Mohammed.

Susan Crawford, convening authority under the Military Commissions Act of 2006, barred the current prosecution against him in January 2009, before the end of the George W. Bush Administration, ruling that that We tortured Mohammed al-Qahtani...His treatment met the legal definition of torture. And that's why I did not refer the case" for prosecution. The techniques they used were all authorized, but the manner in which they applied them was overly aggressive and too persistent. . . . You think of torture, you think of some horrendous physical act done to an individual. This was not any one particular act; this was just a combination of things that had a medical impact on him, that hurt his health. It was abusive and uncalled for. And coercive. Clearly coercive. It was that medical impact that pushed me over the edge [to call it torture]

She did not, however, free him, and is waiting for military prosecutors to file new charges.
