Are red-light cameras about safety or revenue? If there are intersections known to be unsafe, why shouldn't there be something changed to make them safer? For the cameras to be able make money, the unsafe condition has to remain in place.
Things as simple (and inexpensive) as increasing the duration of the yellow and/or all-red period have shown to be as effective as red-light cameras in decreasing the incidence of red-light running. The lights should be coordinated to ease congestion and keep traffic flowing smoothly, not impede it.
Perhaps traffic density has increased or decreased since the installation of the red light, but there has never been a change in the timing or an evaluation to see if the light is still necessary. If you want a revenue increase, make a tax, not bogus safety claims.
