Certain county judges have declared them to be unconstitutional. One of them was Broward County, a very liberal BLUE county, which was a surprise. Judge’s relative must have gotten a ticket or he did!.............
They tried them in California and had the same problem. Just like guns don’t kill people, people do, cars don’t run red lights, drivers do, and people would come to court, say they weren’t driving at that time, and get off. So the state stopped enforcing them. Then the private company running the cameras would send a “ticket,” but there was no way to enforce it so everyone knew to just toss them. After a few years they gave up.
