Check out Senator John McCain’s op-ed in the Washington Post speaking out against torture:
Bin Laden’s death and the debate over torture By John McCain, Published: May 11, 2011 Washington Post
Osama bin Laden’s welcome death has ignited debate over whether the so-called enhanced interrogation techniques used on enemy prisoners were instrumental in locating bin Laden, and whether they are a justifiable means for gathering intelligence.
Much of this debate is a definitional one: whether any or all of these methods constitute torture. I believe some of them do, especially waterboarding, which is a mock execution and thus an exquisite form of torture. As such, they are prohibited by American laws and values, and I oppose them.
