The New York Times will later report that in 2002 and 2003, Michael Chertoff repeatedly advises the CIA about legality of some aggressive interrogation procedures. Chertoff is head of the Justice Department’s criminal division at the time, and will later become the homeland security secretary. Chertoff advises that the CIA can use waterboarding. And the Times will claim he approves techniques “that did not involve the infliction of pain, like tricking a subject into believing he was being questioned by a member of a security service from another country.” [New York Times, 1/29/2005] It will later be reported that the CIA tricked al-Qaeda leader Abu Zubaida into believing he was in the custody of the Saudis when in fact several US officials were merely pretending to be Saudis (see Early April 2002). Furthermore, Chertoff seems to have been advising on the legality of techniques used against Zubaida, strengthening allegations that ‘false flag’ trickery was used on him. “In interviews, former senior intelligence officials said CIA lawyers went to extraordinary lengths beginning in March 2002 to get a clear answer from the Justice Department about which interrogation techniques were permissible in questioning Abu Zubaida and other important detainees. ‘Nothing that was done was not explicitly authorized,’ a former senior intelligence said. ‘These guys were extraordinarily careful.’” Chertoff also opposed one technique that “appeared to violate a ban in the law against using a ‘threat of imminent death.’” [New York Times, 1/29/2005] This appears to match claims that the CIA proposed but did not implement a plan to place Zubaida into a coffin to convince him he was about to die (see Between Mid-April and Mid-May 2002).
