Abu Zabaydah's Interrogator On Torture

Former FBI Agent Ali Soufan's piece in the Times today is fascinating, and will be talked about quite a bit, I assume. But what I'm most interested in is this:

There was no actionable intelligence gained from using enhanced interrogation techniques on Abu Zubaydah that wasn't, or couldn't have been, gained from regular tactics. In addition, I saw that using these alternative methods on other terrorists backfired on more than a few occasions -- all of which are still classified. The short sightedness behind the use of these techniques ignored the unreliability of the methods, the nature of the threat, the mentality and modus operandi of the terrorists, and due process.

I am so scared of what we don't know. What we often forget is that these documents are only part of the picture. God only knows what's yet to be unclassified, or what will never be known.
