Transcript for Sen. John McCain: Torture 'Stained Our National Honor'
The truth is sometimes. A hard pill to swallow. It's sometimes causes us difficulties at home and abroad. It is sometimes used by our enemies. In attempts to hurt us. But the American people. Are entitled to. None of the left nonetheless. They must know. When the values that define our nation are intentionally disregarded. By our security policy is even those policies that are conducted in secret. They must be able to make informed judgments. About whether those policies in the personnel. Who supported them were justified in compromising our values. Whether they served the greater good. Whether as I believe. They stay in our national honor. It much harm. And little practical good. What were the policies. What was her purpose. Did they achieve it. They make us safer. Less safe. Or did they make no difference what did they gamers. What did they cost us. The American people need the answers to these questions. Yes some things must be kept from public disclosure. To protect clandestine operations sources and methods. But not the answers to these questions. By providing them the committee is empowered the American people. To come to their own decisions about whether we should of employed. Such practices in the past. And whether we should. Consider permitting them in the future. This report strength and self government and ultimately I believe America's security in stature in the world. I thank the committee. We're that valuable public service. I have long believed. Some of these practices amounted to torture. As a reasonable person would define it especially but not only the practice of waterboarding. Which is a mock execution. And an exquisite form of torture. Its use was shameful and unnecessary. And contrary to assertions made by some of its defenders. And is a committee's report makes clear. It produced little useful intelligence to help us track down the perpetrators of nine elevenths. Or prevent new attacks and atrocities. I know from personal experience. That the abuse of prisoners will produce more bad than good intelligence. I know that victims of torture. Will offer intentionally misleading information. If they think they're chat their captors will believe it. I know they will say what ever they think their torturers want them to say. If they believe. It will stop their suffering. Most of all. I know the use of torture compromises that which most distinguishes us from our enemies. Our belief. That all people. Even captured enemy yours. Possess basic human rights. Which are protected by international conventions. The United States not only joining. But for the most part office. I know too that bad things happen in war I know and war good people can feel. Obliged for good reasons to do things they would normally object to and recoil from. I understand the reasons. It governed the decision to resort to these interrogation methods. And I know that those who approve them and those who use them. We're dedicated to securing justice for the victims of terrorist attacks. And to protect Americans from further harm. I know their responsibilities. Were grave and urgent. And the strain of their duty. Was owners. I respect their dedication and appreciate their dilemma. But I dispute wholehearted. That was right for them to use these methods. Which this report makes clear. We're neither in the best interest of justice. Nor our security. Nor the ideals we have suffer five's we have sacrificed. So much blood and treasure to defend.
