Gunfright: Routine at 46873

46873: Handle Bystander

Type 6: a bystander who wanders about the town. He goes away when the sheriff is more than two cells away. If he is shot, the bullet turns into a puff of smoke, the fine is taken from the bounty and the bystander dies. If the sheriff on foot touches him, the sheriff dies; if the mounted sheriff does, the bystander dies.
