These were removed all across LA County years ago here. There was about an 80% increase in collisions at those intersections. City traffic engineers said photo enforcement caused more rear-end accidents because people are scared when they see a yellow light at a camera controlled intersection and slam on their brakes.
There is nothing rooted around public safety with those cameras. It is ALL about revenue.
While I don't advocate running red lights, sometimes the safer thing to do is roll through a yellow knowing there's a possibility it may turn red when you're in the middle of the intersection. Depending on your speed and whose behind you, it's sometimes more dangerous to try stopping.
I understand enforcing the law, but $500?!?! My state has light cams (my GPS even alerts me of them). A friend and work colleague once went to court to fight one and got it dismissed. The magistrate basically told her that the state is dismissing the charge anytime someone fights it, because they don't want to have a legal battle and have them overturned for being repugnant to the state's constitution.
