I say we get some info from them. I think the following would get them to talk....
Line up 5 or 6, seated side by side in steel folding chairs or the like. Have them naked at least from the waist down.
Interrogator approaches the first one and asks for info. "Detainee" doesn't answer. Ask again. Still no answer. Give one more chance. If no answer, slice open his ball sack and throw his nads against the wall.
Move to the next "detainee."
How far down the line do you think the interrogator will need to go?
