You're talking about a 'best case' bit of torture. How many crap bits, or deliberately misleading bits, of information would had to have been extracted before you got a decent bit? How do you select the people for interrogation? How do you select the interregation method? Your 'good bit' of intel would simply be the tip of a very large and very sordid iceberg.
And to take it to the extreme, yes, the odd bomb going off that could have been prevented if we'd 'thoroughly interrogated' dozens or hundreds of people is the price we have to pay for living in a free society with respect for human rights.
I don't think it works like you see in the films or on 24. The only documentary I've seen on how they do it was an SAS program, from what I gather the 'torture' part of it is just the softening up process, so there'll be a sustained period of no sleep, stress positions, white noise and all the rest of it then you get taken to see a trained interrogator who knows how to lead someone into giving up information. The physical part breaks down the mind, they're highly trained so I'm sure they know when someone is broken and therefore not bullshitting, or have the resources to find out quickly.
