I don't think so. The CIA agents were interrogating important sources in accordance with written legal opinions. That's not torture, that's legal. Now that Obama foolishly published John Yoo's memos, the CIA agents are off the hook. Can't prosecute a man for complying with written policy.
The author, John Yoo, was trying to be a useful lawyer at the time. He provided a readable and understandable guide to what was legal and what was not. He answered the question "How far can we go?" (Useless lawyers, of which there are many, furnish bafflegab that can be read both ways) They are after John Yoo, but probably can't get to him 'cause his superiors OK'd it (at least they didn't trash can it). Plus there is a small matter of statute of limitations. John Yoo apparently doesn't think it's illegal torture unless blood is drawn, marks are left, or the subject's health is impared by the interrogation.
Personally, I have no problems with making Al Quada terrorists hurt a little bit.
Some NPR talking head kept raving on and on about "Torture is illegal." So it is. But CIA wasn't torturing, they were interrogating terrorists in accordance with written legal advice.
