I think they should use cameras for red light runners. You can witness a red light runner at almost every intersection during a light signal change. to those red light runners, I cannot think of a situation where running a red light to save 30 seconds is worth the possibility of taking someones life. I am also for no cell phone use while driving, only hands free. 90% of the time you see someone not obeying traffic laws, they are on their phone. And again, I see no situation that is so important that you need to answer your phone or read/send text while driving. If it is that important, pull off the road.
