I'd rather get a ticket for having no front plate than risk running a red light camera with a front plate. Think about it. How often do you get pulled over and get a ticket for not having a front license plate? probably once a year.
How often do i run a red-light camera? Almost every week. Not intentionally but just bad timing.
I would have to get 10 no front plate tickets to equal one red-light running. Still worth it not to have no front plate.
