RE: Going to the gov't for grievances
In our state if such things happened you could call the state police/state troopers and they would investigate with no cost to anyone. If they found a crime such as misuse of funds in the club they would present the case to the DA to prosecute.
The car vandalization problem would probably be hard to pin down and would require local police I believe - tho I'm no expert by any means.
Them breaking club rules and constituion - I can't see you could ever get that to stick beyond misuse of funds.
I'd call the state police on my way to find another club.
