Beat the shit out of the lady's sons and or husband.

Seriously, it may seem like bad advice, but who is honestly that gay to lie about someone commiting vandalization? And what kind of magistrate would do that to someone while they have NO proof you did anything?

Although, you should have denied everything in the first place, like you said.. they had no evidence you did anything. Just deny everything when you go to court, as long as it does not bend the truth too entirely from what you told the magistrate(or whoever the guy was who decided you'd go to court). Get a public defender if a lawyer is required, don't waste money on this petty shit.

And don't believe their scare tactics, either. You'd never get a year in jail. Just a slap on the wrist and maybe a month of probation and/or a revoke of your license.. if you have one.
