One interesting (and alarming) part of this article (toward the end) is the comment by the DEA agent who headed the sting operation that nabbed Bout in response to suggestions that it won't be easy for Bout to resume arms trafficking after being "out of the game" so long and very restricted in terms of where he can travel. The DEA agent, Pasquarello, said, “I think it’s very easy for him to get back into business. I’ve heard that Viktor’s not a threat, that he can’t travel anymore, that he’s going to be isolated. He was like that for 10 years before we arrested him. He knew he couldn’t go anywhere and he still operated from his safe spots.” I figure that if anyone knows how easy or difficult it would be for Bout to resume his activities, it would be this guy Pasquarello.
