As they prepare for the 2014 World Cup, police in Brazil are now testing out new facial recognition shades called “RoboCop” glasses because they are outfitted with a tiny camera. Without walking up to you and asking your name, from up to 12 miles away cops will now be able to use the glasses to scan crowds at 400 faces per second and see if anyone they looked at is in a database of criminals and terroroists. The camera reportedly analyzes 46,000 points on a person’s face so the chance of it being wrong is very slim.
