The number of detainees subjected to these methods has never been authoritatively established, nor how many died as a result of the interrogation regime, though this number could be as high as 100.[19] The CIA admits to waterboarding three people implicated in the September 11 attacks: Abu Zubaydah, Khalid Sheikh Mohammed, and Mohammed al-Qahtani. A Senate Intelligence Committee found photos of a waterboard surrounded by buckets of water at the Salt Pit prison, where the CIA had claimed that waterboarding was never used.[20][21][22][23] Former guards and inmates at Guantánamo have said that deaths which the US military called suicides at the time, were in fact homicides under torture.[24] No murder charges have been brought for these or for acknowledged torture-related homicides at Abu Ghraib and at Bagram.[25]
From the outset, there were concerns and allegations expressed that "enhanced interrogation" violated U.S. anti-torture statutes or international laws such as the UN Convention against Torture. In 2005, the CIA destroyed videotapes depicting prisoners being interrogated under torture; an internal justification was that what they showed was so horrific they would be "devastating to the CIA", and that "the heat from destroying [the videotapes] is nothing compared to what it would be if the tapes ever got into public domain".[26][27][28][29] The United Nations special rapporteur on torture, Juan Mendez, stated that waterboarding is torture—"immoral and illegal", and in 2008, fifty-six Democratic Party members of the US Congress asked for an independent investigation.[30][31][32]
American and European officials including former CIA Director Leon Panetta, former CIA officers, a Guantanamo prosecutor, and a military tribunal judge, have called "enhanced interrogation" a euphemism for torture.[33][34][35][36][37] In 2009, both President Barack Obama and Attorney General Eric Holder said that certain techniques amount to torture, and repudiated their use.[38][39] They declined to prosecute CIA, US Department of Defense, or Bush administration officials who authorized the program, while leaving open the possibility of convening an investigatory "Truth Commission" for what President Obama called a "further accounting".[40]
