I don't support is regular or even rare use. I believe it should be a last ditch tactic that may be used only in such scenarios. It may be an implausible scenario but if it does happen, would torture be a valid tactic?
True. I believe that it gives more false information than true information. But on the rare occasion they will tell you what you want to known.
True. However, you may on the rare occasion actually capture the mastermind or those in the know.
I believe that this is patently false. It may not be effective and it may waste resources but you can realistically state that it is completely 100% never ever works. That's just ridiculous.
To set things straight, I don't believe torture is all that use or even that effective. However, I believe there are rare occasions where it may be necessary to save the lives on innocents. In these situations, which should be exceedingly rare, torture may be the only valid way to get the information required. Any use of such a "tactic" should be properly vetted through legal, public and through appropriateness systems. I may even require that the President of the United States approve these rare events and bear responsibility for their outcomes.
And there are also a few rare events with several Al-queda leaders who did provide useful information under torture. I disapprove of such tactics. Like I said, I don't believe it is that useful but I believe it may and should be used in very circumstance such as the "ticking bomb" scenario.
