torture on 19 July 2008, and stated "the UK unreservedly condemns the use of torture". Arguments have been put forward in the United States that it might not be torture in all cases, or that it is unclear. The U.S. State Department has recognized "submersion of the head in water" as torture in other circumstances, for example, in its 2005 Country Report on Tunisia. The United Nations' Report of the Committee Against Torture: Thirty-fifth Session of November 2006, stated that state parties should rescind any interrogation techniques, such as waterboarding, that constitutes torture or cruel, inhuman, or degrading treatment or punishment. Classification in the U.S. Whether waterboarding should be classified as a method of torture was not widely debated in the United States before it was alleged, in 2004, that members of the CIA had used the technique against certain suspected detained terrorists. Subsequently, the U.S. government released the Bybee memo, a memorandum dated 1 August 2002, from Jay Bybee at the Office of Legal Counsel for White House Counsel Albert Gonzales. The OLC memo concluded that waterboarding did not constitute torture and could be used to interrogate enemy combatants. Bybee reasoned that "in order for pain or suffering to rise to the level of torture, the statute requires that it be severe" and that waterboarding did not cause severe pain or suffering either physically or mentally. A separate memo in July 2002, written by the Defense Department's Joint Personnel Recovery Agency, described the use of waterboarding and other techniques of extreme duress as "torture" and said that its use could yield unreliable information, and warned that "The unintended consequence of a U.S. policy that provides for the torture of prisoners is that it could be used by our adversaries as justification for the torture of captured U.S. personnel." This memo was forwarded to the Defense Department Office of the General Counsel, and then to the CIA's acting general counsel and Justice Department, even as the George W. Bush administration authorized waterboarding and other measures. For over three years during the George W. Bush administration, the Justice Department's Office of Professional Responsibility conducted an investigation into the propriety of the Bybee memo and other memos by the Justice Department on waterboarding and other "enhanced" interrogation techniques. The OPR report findings were that former Deputy AAG John Yoo committed intentional professional misconduct and that former AAG Jay Bybee committed professional misconduct.
