What is the True Story of Torture and its Effectiveness?

Everything I've heard and read about the use of tourture on terrorism suspects says that it doesn't work. When it comes to Khalid Sheikh Mohammed, my understanding is, that he gave up information while we were dealing humanely with him, and then clammed up once the torture started.

But the Dick Cheney/right-wing argument is that torture works, so it doesn't matter that it's illegal. Also, things long regarded as torture, such as water boarding, sleep deprivation, stress positions, isolation, etc. are not really torture at all, because they don't permanently maim or kill you. Usually.

Today on FOX "News" Sunday, I saw for the first time the outright claim that KSM gave up all of his information only after he was water boarded one hundred and eighty something times. I don't believe this is the case, but they said it plain as day. I really, really want to see a rebuttal to this.

Oh, and the stinger that Chris Wallace delivered after Juan Williams said it is not OK for the US to torture? "I just want to point out to the audience that it is purely coincidental that the US has not been attacked again since 9/11." What a colossal dick. Seriously.
