Brazilian police live out Robocop fantasies, test glasses that scan for criminals

In advance of the 2016 Olympics 2014 World Cup (and the thousands of visitors it'll draw), military police in São Paulo and Rio de Janeiro are testing glasses topped with cameras capable of scanning crowds for criminals. The camera analyzes 46,000 biometric points on up to 400 faces per second - data that then gets compared with a database of up to 13 millionpeople. If a mug happens to match a wanted person or known troublemaker, a red light will appear on a small screen connected to the glasses.
