Think about it, a civilian or someone else set a bounty on you that's over 4k. If you're in a public session, you can find a spot to take cover & camp, but at the same time avoid bombs and such. Shoot any f**kers that's trying to kill you. Be clever, and time yourself on how long you can survive with a whole bunch of players chasing after you.
For extra bounty fun, set a bounty on your friends too, and you can help each other out from other players getting the bounty. It's a win-win
