we have them in Minneapolis. the cameras, themselves, have been fought in court. i'm not certain if they are still there as i don't drive in the big city. my brother got a camera ticket in the mail from one of the carolinas, but he deserves to get caught he-he-he. if they work properly, i'm in favor of them. MN's argument is that it punishes the car's owner and not the driver of the car, who could be a different person.
