what im saying is find out by ringing up the cops row ho ever u can and see what vehicle he was driving on the day and see if it was fitted with a speed device, maybe also see if they have a recording of the officer that pulled up over (sometimes they have tape recorders in there pockets) try and get all the info u can think of to fight it to make your case stronger, just so if or when i goes to court, u are not wasting your time and money.
