National Geographic - Explorer, Science of Surveillance (2006.TV Rip)

This video is good. Highlights include using cameras and computers, tracking people using face recognition, picking people out of databases even if the person puts on a fake beard or glasses on. Watch and see thousands of people getting iris scans daily.

Technology being shown that takes x-rays through objects like buildings to see what people are hiding. A car example is used. Also in the video a helicopter spies on the citizens each night in New York.
