http://news.yahoo.com/goodbye-anonymity-latest-surveillance-tech-search-36-million-201818390.html This is like Minority report....but with better technology. I think this tech will keep alot of people honest.
I think it will be a boon to realistic mask makers. Soon we'll have to put on our "face" before we can go outside. We'll be seeing Obama and Bush creating most crimes. Some times together!
They will probably just make it illegal to wear masks. One halloween I was dressed as a skeleton with my face painted like one. I walked into a casino in Vegas and after about 3 minutes security got ahold of me and escorted me out of the building. I told them I would leave on my own, but they wouldnt let me out of their sight. Life would probably be like that...you wear a mask, you are about to do something and they might arrest you. (or some neighborhood watch captain shoots you)
