I think that torture is just a way to get someone to say what you want to hear. Don't really think that it'd be the truth. What they do tell you before what you're doing actually kills them should be taken with a grain of salt. The people that would be tortured would probably have been pre-conditioned so that they could withstand someone beating them until the brink of death.
So, I'm not for or against torture or RAI as the jargon name; ha-ha! I'm just not so confident in the results actually giving me liable information.
It's like beating your wife until she says that she loves you. She actually hates you because you beat her but she says loves you in the heat of battle and you're content afterwards; ha-ha!
