I also think cameras are unnecessarily. First of all, like Stacy said, their are situation were you can't stop instantly. If person saw that camera sign and tried to stop hard, bigger issues can be happen. Plus, I think it is wast of money. If government had enough money to put cameras to each stop light, they should be more concerned in another problems in traffic. (taking out the ice, repairing road, ext...)
There for, I think cameras are unnecessarily for stop lights.
