I was arrested last week for possession of a controlled substance and paraphernalia and let go later that night. I'm pretty sure I was never booked. They said it would take a few months before I was contacted for an arraignment. Do they have to book you if they arrest you? They let me go without having to post any bail or anything so what should I expect? Can I go down to the police station and get a copy of the police report, or do I have to wait until I go to court?
