that's ********....reminds me of something that happened to me last summer:
i pulled into my driveway around 12:30 A.M. or so, maybe 1 A.M., and get out of the car just as a cop pulls up in front of my house. I live in a quiet neighborhood, very little goes down in my town, so a cop showing up is something rare. I said "evening, officer, anything i can help you with?" he asked me if i had been over near Alexander Avenue (street off of Rt. 23). I told him no, i hadn't been over there. He said he saw two tire marks going across Rt. 23. I told him again, I wasn't anywhere near Rt. 23 that night (which i hadn't been). He said he was just making sure, and drove off. If he had pressed the issue, I would have brought up the "two tire marks" thing, since my Camaro has an open diff. Impossible for me to leave two marks
Go to court, and fight that ****. If they have no proof, then the case will be tossed out.
The key thing is PROOF. the burden of proof is on the state/town, etc. if they have no proof, they can't convict you.
