It comes to my mind a passage of a book written based on interviews of a drug dealer of Rio de Janeiro and the community of its favela, in which they explain a technique they used when they (the drug dealers) were tortured by the police. It went something like this "For the first hour or so you say nothing, because they won't believe you anyway. After you start to break, you start spilling names of already dead colleagues of yours, and facts that are true but already happened. That should buy some time while they check the facts and see they are true, until they figure they are irrelevant".
This is the
book, but it is in Portuguese. Dunno about an English version, but it is rather short and very interesting, so if you find it, I recommend it.
