Well, this whole thing was preventible by the OP in my opinion. (IF it's a true and real posting, which I'm doubting).

First of all, you got a pit bull and didn't bother to find out if it was illegal or not. Secondly, you took your PIT BULL to a park and let it off leash. Shame on you. Pit Bulls don't belong at parks, especially dog parks. And you made the really bad decision to let it off leash, intentially breaking the rules of the park.

It's people like you who are putting these dogs in the very perilous position that they're in. Irresponsible and uneducated people are the reason my dogs my eventually be deemed illegal.

Sorry if it sounds harsh, but that's JMHO.
