Quite right, Andy.  I, too, used to live where red-light cameras were, and still are, in use at PREVIOUSLY dangerous urban intersections. They're very effective.  Longtime residents there said that the many crashes dropped off dramatically soon after they succeeded in getting lawmakers to add the technology to help catch red-light runners.  And, because they're serious about public safety, they also opted for serious penalties for such inexcusable reckless driving, starting with $500 fines and 30-day license suspensions.  So impulsive young drivers are less likely to develop the deadly belief that they can get away with murder (or vehicular homicide).
