its not just people that don't know anything. People that do can and have gave bad intel knowing that it would make the torture stop and you waste time/resorces. granted those are only the "hardcore" and are very rare.
I'd really like to know the truth about how much good intel we actually get from doing things like this.
No one is ever going to release that info
i'd bet we get very little..
You don't suppose our intel guys have figured that one out? Of course the info has to be vetted, maybe by waiting a few days and hitting them again with the water and see if the story is the same. Very simple as a start.
What I find most interesting is that our own military has stopped waterboarding its own ranks as a means to toughen them up in case they are captured. It turns out it is so effective, they had 100% giving everything up - accurately. And this was among Seals, Spec Ops, Green Berets, etc., not just the rank and file. That says a lot about its usefulness.
bho's ploy was to expose our secrets to the world to shame us as a country and to make our intel people's jobs just that much harder.
