This is a “do both” situation: those “honest people” are still knowingly trying to cheat their neighbors, so while they pose less of a threat individually than the people with fake plates the aggregate cost is quite high due to greater numbers, and fining them is done by a separate group of people so it doesn’t take any resources away from the police you need to go after the hardened criminals. Cameras actively help that process, too, because they collect data showing how widespread the problem is and individual fake plates will collect tickets showing how dangerous those particular drivers are.
