Even John McCain admitted that torture does not work...and he should know.
Let's revisit this statement.
From Faith of My Fathers by John McCain
"Are you ready to confess your crimes?"
"No."
With that, the guards hauled me up and set me on the stool. They cinched the rope around my biceps, anchored it behind my back, and then left the room....I remainded there for the rest of the night.

On the Fourth day, I gave up.
(McCain signed a hand written confession and recorded the confession on tape.)
I was returned to my cell and left alone for the next two weeks.
They were the worst two weeks of my life. I couldn't rationalize away my confession. I was ashamed. I felt faithless, and couldn't control my despair.

Many guys broke at one time or another. I doubt anyone ever gets over it entirely. There is never enough time and distance between the past and the present to allow one to forget his shame.
Sounds like McCain may think torture does work.
