Think Progress, under the category 'radical rightwing agenda', informs us that John Ashcroft was asked at the University of Colorado if he would be willing to be subjected to waterboarding.
Apparently, Democratic Representatives Jerrold Nadler and William Delahunt have introduced the American Anti-Torture Act of 2007 which would outlaw the practice. This is good: we need clarity on this issue so those fighting the War on Terror know if waterboarding is legal or not. The fact that clarifying legislation is necessary rather proves that waterboarding is not an illegal practice. And if Torquemada himself is willing to be subjected to the practice, well, is that not also proof that it is not only legal, but also not tortuous as well? Remember: no one ever volunteers to undergo real torture.
