Anybody can be made to talk, just depends on the strength of the man's will and how far below the line of fair play the interrogator wants to descend to get the information. Or so I am told.
In any case, the sad fact is that there are plenty more where this one came from, including I suspect, in Pakistan's security service--- so I don't see a quick end to it even if this guy can be made to talk. Certainly would put a dent in their standard mode of operation however.
