Ask them to send you a copy of the camera calibration certificate
A friend of mine got caught. He was told my someone that they don't keep on top of the calibrations alot of the time. the same way they can't afford the gatzo cameras
He asked for a copy of the calibration certificate and they dropped the charge.
