“Torture is not tolerated by this country on the battlefield or off. Anyone who tortures or abuses a detainee tarnishes the service of every honorable student and soldier in this room today. The President has said this, and I will say it again: those who commit torture in the name of the United States government will be prosecuted. In any discussion of Guantanamo, detainees and military commissions, I think that one final fact helps put things in perspective — and that is the fact that members of al Qaeda are not merely common criminals. Some critics around the world have argued that they are “just” criminals, that their crimes somehow do not amount to war crimes. But here are the facts: al Qaeda seeks to employ weapons of mass slaughter as a means of achieving political goals against both the civilian and military capacity of the United States, Europe, and our allies throughout the world. Its members continue to fight our Armed Forces on battlefields around the world, and they will continue to do so until we stop them. Al Qaeda has committed acts on a scale that transcends mere crime, as recognized by NATO immediately after the attacks of September 11th. Their crimes are therefore nothing less than war crimes. Given the magnitude of the atrocities al Qaeda has committed, there can be no comparison between the crimes of its members and that of common civilian criminals.”

Signing statement on the ratification of the United Nations Convention on Torture http://deadconfederates.com/2014/12/10/prosecute-them/ (1984)
1980s, First term of office (1981–1985)
Context: The United States participated actively and effectively in the negotiation of Convention. It marks a significant step in the development during this century of international measures against torture and other inhuman treatment or punishment. Ratification of the Convention by the United States will clearly express United States opposition to torture, an abhorrent practice unfortunately still prevalent in the world today. The core provisions of the Convention establish a regime for international cooperation in the criminal prosecution of torturers relying on so-called "universal jurisdiction." Each State Party is required either to prosecute torturers who are found in its territory or to extradite them to other countries for prosecution.

On claims of waterboarding as being impedimental in as quoted in "John McCain to Bush apologists: Stop lying about Bin Laden and torture" by Greg Sar in The Washington Post (12 May 2011) http://www.washingtonpost.com/blogs/plum-line/post/john-mccain-to-bush-apologists-stop-lying-about-bin-laden-and-torture/2011/03/03/AF10AnzG_blog.html - YouTube video of McCaine's speech http://www.youtube.com/watch?v=3I94Yb4KUic
2010s, 2011
Context: We did not learn Abu Ahmed’s real name or alias as a result of waterboarding or any "enhanced interrogation technique" used on a detainee in U. S. custody. None of the three detainees who were waterboarded provided Abu Ahmed’s real name, his whereabouts, or an accurate description of his role in Al-Qaeda. … In fact, not only did the use of "enhanced interrogation techniques" on Khalid Sheikh Mohammed not provide us with key leads on bin Laden’s courier, Abu Ahmed; it actually produced false and misleading information. Khalid Sheikh Mohammed specifically told his interrogators that Abu Ahmed had moved to Peshawar, got married, and ceased his role as an Al-Qaeda facilitator — which was not true, as we now know. … It was not torture or cruel, inhuman, and degrading treatment of detainees that got us the major leads that ultimately enabled our intelligence community to find Osama bin Laden. … we are again engaged in this important debate, with much at stake for America’s security and reputation. Each side should make its own case, but do so without making up its own facts.

Responding http://www.youtube.com/watch?v=Tiyezo1fLRs to Senator José Agripino Maia - former member of ARENA, ruling party of the military dictatorship - in a Senate hearing, May 7. He suggested that, for having lied when she was interrogated by the political police, she could also have been lying about the leak of data of Fernando Henrique Cardoso's personal expenditures.
