I would think that the Deputy chief of the CIA's interrogation program should know what he's talking about when he said that waterboarding was ineffective.
Yes, one would think that, but then one wouldnt expect anyone to spend millions of USD on research telling them that water is wet either.
Political Correctness demands that everything we can learn through history and common sense be dismissed in an appeal to objective authority that is neither objective nor authoritative. Any prisoner can tell you that when the torture starts most people will tell them anything that they know, and if they dont know anything they will insist on ignorance then finally just start making things up. Interrogators that know what they are doing can sort through the bullshit from the fact, but that obviously doesnt include people who need millions of USD in research to show them how its done.
But that aside, when the tables are turned and we are not looking at the problem from the targets point of view, suddenly all that 'I would sing like a Canary' stuff flies out the window and suddenly the world is full of iron man heroes who will die of pain rather than give up any actionable intell.
Give me a break.
