If we got him(killed him) or captured him, and I was the general or what ever in charge. I would not tell the whole world, at first..... You never know, maybe the terrorists would increase their actions and double their efferts to avenge their leader..... who knows....
Hell, If I was the soldier to kill him/capture him, I would be running my mouth off so much like idiot, that i'll get shot in just a few hours. So, what i'm trying to say is, if i saw him, i'm gonna run. I ain't gonna get shot by my own people.
(For the slow that don't comprehend sarcasm....that was sarcasm)
There is a time when immediate justice is just as effective as the courts. However, I would most definitely pry information from him.
*Edit* Do you think he'd let himself be captured?
Cut off the head and the body will die? Unless terrorism is a hydra - which it probably is.
