I don't doubt we obtained valuable intelligence through torture. It is still torture.
I think it would be interesting to turn the CIA loose on you for a few years and see whether you still agree that it should be part of the toolbox. Or maybe render you to the Saudi's and let them go to work. Submit to that for, say, 3 to 5 years, and I'll listen to your opinion on this.
Also, I suspect you agree that when our boys and girls get captured fighting abroad, torture is fair game, because, its an effective way to gain intelligence and because, you know, we torture, so fair's fair.
