Thanks Simon-right on about fear/terrorism. Goes along with that dang bumper-sticker "An armed society is a polite society," no, an armed society is a frightened society. That's not politeness-it cowering. I don't want to cower nor live in fear. Don't want others to either. 

It's not about who wins-it's about how do we all live together.

Oh, and as to cameras at traffic lights-could we get some on the medians, too? Get those big honking four-wheel drive vehicles who either can't wait for their turn to get to the turn lane and drive half on to them to bypass stopped traffic, or cross them completely to go to the McDonalds across the street.
