<< but he said he didn't clock me, but paced me with a car next to me that he clocked doing 80mph. >>
I guess my argument would be that he didn't clock me, he clocked someone else. If he was gauging my speed by the car next to mine, he can't really know who he clocked and at what point he clocked them. The other car could have slowed down 5 or 10 mph by the time the police officer looker from he radar gun to the car or he could have clocked someone in another lane. If he did in fact clock the other car at 80, why didn't he pull that car over. This sound fishy to me. If he never clocked you, I would challenge it, there are to many things that could be put into doubt. He does not have a radar reading on your car, so he can't really prove that you were speeding.
