There should be like a combine NPC next to the jail. Pressing your use key on him will send you to jail if you have 1800 crime or more. You can also decrease the player's jail time by 25% for confessing to doing crimes.
There needs to be some kind of system since the only way to reliably go to jail is if someone kills you while you have a bounty or if a cop jails you.
