Well, I've got some bad news unfortunately. Torture does work. Not all the time but there are plenty of cases where torture has directly led to such plots being discovered and dismantled before they could come to fruition. If your only defense against torture is an efficacy one, then you've lost the argument. I'm engaged with two other posters over exactly this problem. You can want to believe that it's ineffective. Hell, many people do! But at the end of the day, if you don't oppose it on moral/ethical grounds, and you honestly do think you would be negligent in NOT torturing someone in the scenario given, then you should support torture.babinro said:100% Absolutely torture the person.
This specific scenario makes it seem negligent to simply let the event happen.
I'm completely against torture in real life because situations are never going to be this clear cut. I'm told that torture in real life is an ineffective means of getting reliable information. I want to believe this to be true. So being able to apply this clear cut 'greater good' rationale no longer works.
I don't agree though that torturing someone for information is okay, no matter what the outcome and no matter how sure you are that the information is reliable. If torture really didn't work, the CIA wouldn't do it. It does work though, often enough for it to be rationalized if you don't care about the moral and ethical problems.
