Their argument is weak.
What with all the traffic cameras coming on these day's, if anything they will be cracking down on the whole front plate thing.
back when I never had mine on (before I was cited for it) I used to go through an intersection in La Jolla with a camera, I saw that thing flash in my face 2 or 3 times but with no front plate, no ticky ever showed up in the mail.
