I think the offenses now are just fine. Maybe in the future , there will be more charges that can be straight to jail. But keep in mind, most straight to jail offenses involve prison breaks, or bounty hunters. If you feel you aren't being treated properly or are getting a great RP experience, try your best to keep the story going, keep in mind the cops don't have to believe your story, but there are some cops that go above and beyond to give civs a great experience.
