The jails would end up being overfull with all the players who want to be outlaws. But it is a good idea, maybe they can implement it.
Cowboys didn't duel. They herded cattle, and hired out as labourers.this would be more like "the west" where cowboys had to fight other people including the sheriff before duelling the player
The sheriff can sit on his butt in the saloon he just needs to hire a few deputiesthere is a sheriff in every town, but he's an alcoholic, has another bottle of whisky every time i see him.
