That's not an argument people usually make against red light cameras. The usual arguments are...
* Camera installation is usually accompanied by shortening the yellow light period to increase revenue, which leads to more accidents.
* Most red light camera tickets are for rolling right turns on red. Such a violation rarely leads to accidents. These tickets are more for revenue than safety.
The second point here is a big one. Quite a few cities in California make significant revenue off ticketing rolling right turns, because they can argue the vehicle code is ambiguous enough to let them ticket it under the infraction for running the light (which is $500 plus a couple hundred extra for traffic school if the driver doesn't want to get points on their license). There's a bill that's perpetually in and out of the state legislature to close that down and make it absolutely clear that a rolling turn is a lesser violation (one with a fine too low to be worth the cost of enforcement), but it mostly tends to get shouted down by cyclists who think the oversize fine protects them.
