Contact an attorney who specializes in self-defense and firearms issues, if you can find one. If not, a criminal defense attorney is probably the next best thing.
The problem with contacting your local law enforcement agency is, sadly, the individual you talk to may, or may not know what he or she is talking about. Worse still, they may know, but deliberately steer you wrong. In som jurisdictions this can be a real concern.
This being said, contact local law enforcement anyway. Just don't take their advice as legal advice. The value in contacting them can be as important as legal advice though. It can reveal the attitudes, of both the individual officers and the administration.
