Suppose for a moment the city found a dangerous pothole in the roadway and instead of fixing it, merely installed a camera nearby to photograph you slamming into it.
Would you find that disturbing?
Now suppose the city identified an intersection with a high number of red-light runners, and instead of fixing it by applying proven engineering countermeasures we know substantially reduce red-light running, the city simply installed a camera to take your picture and sent you a $75 ticket?
I find that equally disturbing. Whether we find a pothole or an engineering flaw, we should fix it. But the financial feasibility of red-light cameras literally depends on identifying an intersection with a high number of violators, and not fixing the flawed timing that produces it.
