If an Ambulance or other emergency vehicle is coming up on you and you are stopped at a red light, you are supposed to pull over and let them pass. But you might have to move forward into the intersection to get out of the way. You would be breaking a traffic law; entering the intersection against the red light. It's for a good cause; you may be saving some person's life, and a real cop would recognize that and give you a pass.
But what if the intersection is infested with red light cameras? Would you still roll forward and pull over, knowing you will get flashed, ticketed by mail and then have to take time off work to go explain yourself to the traffic judge? The judge would probably dismiss the ticket, but you are still out the time and aggravation.
