"Enhanced interrogation technique" is an uncontroversial, accurate factual description. "Torture" is a conclusion of law applied to the facts that, while there is overwhelming reason to accept that the conclusion is valid for the program as a whole, and many of the specific instances in particular, does not necessarily apply to all of everything that is under the label "enhanced interrogation techniques", and is, in any case, not a legal conclusion that the Committee reached (though the Chair of the Committee, Senator Feinstein, in her introduction to the release, emphatically and directly states as her personal conclusion both that the program involved "torture", and that it involved "cruel, inhuman, and degrading" treatment (both terms being significant in regard to grave breaches of the Geneva Conventions of 1949 (including Common Article 3 of the Conventions, which applies to conflict that is not between states-parties to the convention) [0] and the manner in which grave breaches of the Conventions are incorporation into US criminal law as war crimes under 18 U.S.C. Sec. 2441 [1].)
