All the scientific evidence disagrees with you and so do many former employees and directors of intelligence agencies, so I'd like to see some citations. You don't even have to go into physical torture: recent history is filled with cases where people confessed to crimes under police interrogation, only to have iron-clad evidence show up that they couldn't possibly be responsible. The most effective technique is befriending the suspect, doing nice things for them, then allowing the natural human tendency to reciprocate (and a desire for positive social interactions) work for you. It takes time but gets you much more reliable information - and much more extensive information.
