From Mission: Impossible
What, can we do Barnes... put a guy at the airport? How many identities do you think Hunt has? How many times has he slipped past customs and in how many countries? These guys are trained to be ghosts... we taught them to do it for Christ's sake.
Well what do you suggest?
Let's not waste time chasing after him, just make him come to us. Everybody has pressure points, Barnes. You find something that's personally important to him and you... squeeze.
