Please, give me some credit, and don't erect such strawmen and expect me to treat them seriously.
I'm saying that torture doesn't yeild results that are in anyway consistantly reliable. In the absence of working crystal balls, there is no way to tell beforehand if torturing a prisoner would yeild positive results. With such spotty chances would any reasonable human being truly advocate the descent into barbarism? I would hope not.
One word: war.
War is barbarism. Fire bombing Tokyo was barbarism(but necessary). I don't advocate torure for sadistic pleasure and not for any and all terrorists. But there are times when it might be necessary to forget the rules, turn mother's picture to the wall and do what has to be done. I know I won't lose any sleep over it.
