Secretary of Defense Donald “Rumsfeld received a November 27, 2002, memorandum from SOUTHCOM [Southern Command, which is responsible for all U.S. military activities in Central and South America] requesting his approval for the use of various interrogation methods at the Guantanamo Bay detention facility. Back in October, GTMO had developed a comprehensive list of such techniques. Category I included four methods that were well below the limits of the Geneva Conventions. Category II included twelve techniques that were technically within the limits, but could be considered beyond depending how they were implemented. And Category III listed four methods that were clearly beyond the limits of the Geneva Conventions no matter how they were implemented. On December 2, 2002, Secretary Rumsfeld approved SOUTHCOM’s request to use all interrogation methods in Categories I and II, and one method in Category III.”
