Interrogation and torture remain poorly aligned. Proficient interrogators eschew torture for the same reason that modern physicians no longer use leeches and advertise their expertise by wearing blood-stained scrubs into the surgical suite. These things just don't work. Perhaps there is some highfalutin philosophical summit from which to look down on bloodletting as a primitive form of medical treatment. But the effectiveness argument surely casts any sanctimonious argument aside as inconsequential in light of the current understanding of medicine. Similarly, good interrogators don't torture not so much out of affronts to their fine sentiments about slippery slopes and moral high ground as out of the ineffectiveness of approach. Torture does not work because the person tortured will say anything to make the torture stop, thereby casting into doubt the credibility of the intelligence so gleaned.
If one accepts this operational axiom about interrogation and torture, then why would water boarding work, regardless of whether it really is torture or not? Consider: the best interrogation techniques involve uncertainty and exploiting the prisoner's own fears and imagination while stopping short of realizing them. Perhaps what made water boarding effective is that the enemy had no idea of what it was or where it would stop, thereby reducing the value of his training on how to resist standard interrogation techniques.
My own experience under interrogation would tend to support this hypothesis, as I had no trouble resisting standard techniques but found extended periods of sitting blindfolded and handcuffed on a concrete slab surprisingly more enervating than being manhandled and questioned aggressively. In the age of You Tube and perpetual questioning of our own national motives and resolve during political contests, do we leave any doubts for our adversaries about to expect, even if water boarding were to resurface to unprecedented levels? Forewarned, they have no reason to magnify their own fears, hence no way of helping us psychologically by according more mystery and success to our tactics than the tactics alone merit. Consequently, the greater the debate and description of water boarding, the easier it will be to resist and the less value it will have as an interrogation tool.
