I think the judge is right on the issue of the amount of the fine, but I would like to see the tickets handed out by the method of the “red light cameras” to be declared unconstitutional. They go against presumed innocence until proven guilty as they operate, usually, on the assumption that the owner of the vehicle was the driver at the time the vehicle ran the red light - part of the presumption of such tickets and maybe why the fines are less. But, instead of the law having to prove the owner was the driver, it is presumed they are and the tickets are usually allowed to stand.
Frankly, I an personally opposed to all government cameras in “the public square”; that is anywhere outside of any government, or private, building where such cameras may be used for security reasons for that location. But, outside of such facilities, it is our Liberty that is supposed to be “secure”, not the convenience of “law enforcement”.
