I'll go with what works in a timely fashion, though I think torure works. I know I'd spill my guts quickly...
And an awful lot of the people we let go show up fighing us again. I don't think I'd do a catch and release program - unless I was relasing 'em from 10,000 feet up, over the ocean, with no parachute.
The question is, is it effective? (example: what the NV's did to American POWs, what information did they get?) From what I've read about it torture is not and never has been effective in getting intel. Also I wonder what torture does to the interrogator? nothing good I suspect.
