Again. Your ideas about real life are entirely wrong.

Why would it matter that the info they give is "something you know and something new"? How would that stop the "something new" part from being something that was invented to get you to stop torturing them? Of course the most realistic lies will include elements of truth and reference other stuff you think you already know.
And why would merely being "linked to the case in question" mean you can KNOW they have info they aren't willing to volunteer that would help at all, much less that would crack the case? (Sometimes a taxi driver is just a taxi driver.)
Not everyone "linked to the case" is a criminal, terrorist, despicable sub-human scum, or what-have-you.
That is not a popular idea in many areas of the military or law enforcement.
A poem by Erich Fried comes to mind... "don't doubt those who say they're afraid, but be afraid of those who say they know no doubt" -- I guess doubly so if they put torture in quotes.
The only interesting source arguing for the effectiveness of torture was this: http://wikileaks.org/wiki/Torture%2C_interrogation_and_intel...
It seems like torture would work, not in a "ticking time-bomb: scenario, but in a situation where you had a long time to corroborate intelligence gathered from torture with other sources. Interrogate the captive on stuff you already know about, and if they lie, punish them with worse forms of torture. And if people are prone to losing their minds under torture - you can merely submit them to one session of brutal torture, then leave them for a few weeks or months before resuming normal interrogation - with the threat of more torture if they don't comply.
ETA: Downvote demonstrates the point.
You say I'm not leaving room for good faith discourse. I asked for an example of torture saying a life. I asked because, time after time, in all forums, no such example has ever come up.
The real problem is that torture has been allowed to approach too close to where it's considered OK to use.
