Instead of a "law against texting while driving" WHY NOT concentrated education showing WHY you shouldn't i.e. you can't stop your car at 50mph if you are looking at your phone!
Practical illustrations of "do unto others" would cut down the growing mentality of the need for a "cop on every corner"!
When I was in school there was a concentrated effort to teach us that killing, stealing and lying were wrong. I guess we don't need laws against those actions, then. If education alone worked, we'd have a perfect society. We need the laws, because some people don't get the message without a kick in the pants.
