Minor detail. Have you looked around lately? How many times a day do you have you photo taken? Can you drive down the street without the gov knowing your route? Cell phone tracking, photo tracking, store security tracking...nothing new here...move along.
Probably far more than others given the environment I work in. I have card-in twice just to get to work, and pass quite a few cameras. But I chose that.
This is bad mainly because of the danger to free, anonymous speech.
