Yes, it's a well documented fact.
1. The torturer doesn't believe what the suspect says before being tortured so even true information freely given is classed as false.
2. The suspect says anything and everything until the torturer hears what he wants to believe to be true so false information is classified as true.
To know whether the information is true or false means that you need to already know the answers ... so why torture?
Pretty basic, blindingly obvious and very well known ... but not as jingoistic and appealing to the likes of Bush and his supporters.
