I used to be the point man for a company here in Georgia. I would zip in to town, locate your ass and call in the big guys. I would sometimes have to make the pickup myself or lose contact with the subject. You should see how co-operative people get when you make a hole in the side of thier car you could put your hand thru with a deer slug, and tell them thier chest is next. I still have my Spas 12 shotgun. Good money. We didn't bother with any thing under $100k. We also go by the more polite name of skip tracers.
You're right about we don't kill but I have given more than one fool who thought he could get the jump on me, a right nasty limp.
I bet if you had some redneck good old boy bounty hunters looking for Osama, He'd already be in custody...
