Camden? What are you telling me for?  It's 3 in the morning. I’m on my way home. Send a jug-head from the Academy. They will be happy to go pick this kid up.
I can't just send any one in uniform. The feds demanded a senior detective. The kid is a high value subject. I don't know. Just pick him up. Escort him to the Hoover building in Washington.  They had some kind of computer breech there this morning.
Right.
