The cop can present a print out which alot of the time (military cop) we attach it to the ticket when it goes to court for civilians. If using a lidar you wont get a print out there but we can bring it back to the office and print it off. You could go in and use the defense of when was the last time his car/radar was calibrated.Alot of times the undercovers just get a basic car with plug in lights. yadda yadda. there is defense but... you might want to get a traffic lawyer to lower the blow.
