Dude, it was Sunday, I had more important things to do than answer silly questions on the interweb, and now its Monday morning and I have patients to tend to so I will allow my colleague, Cardinal Fang, answer for me.
Thank you Ustwo.
Aggressive interrogation methods are often misunderstood. The classic example would be something like the Spanish Inquisition, where....
Nobody expects the Spanish Inquisition!!!
Ummm yes. Well in the Spanish Inquisition, torture......
NOBODY expects the Spanish Inquisition! Our chief weapon is surprise...surprise and fear...fear and surprise.... Our two weapons are fear and surprise...and ruthless efficiency.... Our *three* weapons are fear, surprise, and ruthless efficiency...and an almost fanatical devotion to the Pope.... Our *four*...no... *Amongst* our weapons.... Amongst our weaponry...are such elements as fear, surprise.... I'll come in again.
Cardinal Fang: No please don't. Well in something like the anishpay quisitioninyey, torture achieved confessions due to the unpleasent fact that people just wanted the torture to stop and would confess to almost any sin, even if the end was death in order to end the torture. A more modern version could be the torture done by the Soviets in order to get people to confess in show trials. This is of course far different than the use of directed torture in order to extract specific pieces of information.
Quite bluntly this was a silly question as the interrogation would not be used to get people to confess they were terrorists, thats just silly, but to find out dates, targets, contacts, and other verifiable pieces of information. You are assuming it would be used on everyone caught. If you nab a guy with a one way ticket, a vest full of explosives, and a picture of Osama in his pocket, odds are you are not dealing with an innocent man. Likewise you are assuming that someone arrested due to association with said terrorists and questioned is going to get the electrodes on his genitals until he says something 'we want to hear' which would have been just peachy if we wanted to put on a show trial, but is worthless to us and we are not stupid enough to waste our time doing so.
