I remember many years ago reading the findings of a study done by the US military about the info that they got out of people at Guantanamo Bay, and basically running out into a field and shouting "Are there any terrorists here??" was more or less as useful, and any field info -regardless of how much or how little - was way more accurate and useful. By the time you even get somebody in front of the torturers, what they know is probably outdated, and you're more likely to get false info than anything true anyway because people will tell you whatever you want to hear to make it stop, even if they have to make shit up right then and there.
