I hate to break this to you, but how do you think the US got all of those al queda guys they captured to spill the beans? I mean, this guy is like the Operations planner for the whole network and you think that because the great evil finally nabbed his ass he's gonna talk? Yeah, right.
The prefered method is to wait until they come out of surgery or some other thing where they had to be sedated and hit them up when they are in the twilight. Besides, im pretty sure that drugging is not covered under the geneva convention ( like anyone listens to that besides us anyway)
