I jump lights often and even do so in front of cops. The one time I was pulled over for doing it, I didn't get scratched. There's the law and there's the spirit of the law. The last time I did it in front of a cop was to get the jump on some dingus who was eating a bowl of cereal behind the wheel at a light. He saw me looking at the dingus, looked at the dingus and shook his head. There's no way he was going to pull me over for that light jump.
