If you're a wanted man and hang out in a crowd of 70K at a concert you probably think you'll be just fine as long as you keep a good eye out for police. Wrong. In China they are increasing their use of facial recognition and putting up security cameras everywhere. The wanted concert goer felt he was safe in a crowd, but he thought wrong and the cops got their man. This is kind of scary if you think about it in a 1984 sort of way. How long before the government knows every step you take? Authorities in China are increasingly turning towards technology, raising concerns around privacy in a country that has plenty of surveillance cameras and wants to build a national database of faces.
