Did all that. As for citizens arrest, they said can't because he is a minor. When I complained once about this kid shooting animals on my property with his compound bow, the cop said "wait till he hits someone and then call Judge Judy" (direct quote).
We are talking Daytona police here. I am good friends with some of them, but some of them are sitting on their butts waiting for their pension.
That sucks. Well, maybe if the police are that useless, you should just get your own BB gun and deal with him that way :-) If they can't be bothered to arrest him, why would they bother to arrest you?
