The so-called red light cameras were being used in Southern California up until about a decade ago. Their use was challenged in civil court by a lawsuit that claimed they were mostly a revenue-creating practice as opposed to mainly being a public safety venture, and because there was no way for motorists to “face their accusers” in a court of law. Receiving a photo-citation and a demand for payment in the mail was also seen as an invasion of privacy by the backers of the lawsuit. Both the local government and the manufacturer of the cameras/accompanying technology we benefitting greatly from the high fees, and the manufacturer was exempt from liability or redress.
The legal fight went back and forth for a while, but the final outcome was that all of the cameras were ordered to be taken down, and if I remember correctly, many people who had paid the fines received reimbursements.
Part of the irony here is that the government presented evidence that the camera system was effective in catching a high percentage of people who ignored red lights, however, the plaintiffs presented evidence that the actual numbers of accidents, injuries, and deaths at red lights were not lowered very much in comparison to the numbers of citations. That’s how and why claim of a “money grab” was successful in the lawsuit.
