Perhaps they do save lives and perhaps they make people think before they go through them but let me tell you my experience. I was in Wilmington for a doctor's appt. Several weeks later I get a bill from the city saying that I ran the red light and they even sent a picture. Problem was, the picture showed me sitting behind the white line at the stoplight. I didn't run it. Since I live quite a distance away, I didn't want to go to Wilmington to fight it so I just sent in the check and a copy of the picture. Not a word from them - but they did cash the check!
