Contact a lawyer and get an opinion that means something.
Get your hands on a copy of the police report, then do what SOB said if it doesn't answer your questions.
You could also get in touch with a commander in the department to get their story, but your lawyer would probably advise against that so you don't make any statements that could hurt a possible future case. Your call as to whether you do that, as your lawyer has a vested ($$$) interest in keeping you shut up and doing it himself for a few hundred bucks an hour. I wouldn't recommend talking to people at the department if you plan on going to court, as something you say will come back to haunt you.
Also, most of the posts here don't apply, as laws vary from state to state regarding most of this stuff.
