If the cop was not yet in the process of writing the ticket and was not near your car. Then no.
It is generally understood by most folks in the civilized world. That if a cop is at your car writing a ticket. 1, You inquire politely as to what the issue is. and try and sweet talk your way out of it. 2, If you feel that the cop has in fact slighted you and was unjustly giving you a ticket. Take that ticket and go to court. Taking the parking valet with you as a witness. Although the video clearly shows no front number plate. So. there's no question the cop had a valid reason to issue a ticket for improper reg.
But the minute you get into your car while the cop is looking into your front window yelling stop 5 times and continue to try and drive away. That changes the game. And will clearly give the advantage to the cop.
