Is that state park... police, or state... park police? Do you mean parking police who are state troopers or is there a state police force called state park?

We only gots state and federal police here. Our State forces do everything your local cops and State Troopers would do. Our Feds are not like your FBI though - they only handle things like International Airports, Aviation Law, counter terrorism, human & narcotics trafficking (together with state forces), some missing persons stuff, cyber-crime, Policing of Australian Territories, Foreign Peace Keeping Operations, etc.
