Presently police there have another weapon with which to battle crime and catch hoodlums: high-tech glasses that take into account facial recognition at the push of a button.

As the Hong Kong Free Press reports, in the city of Zhengzhou, four cops have begun wearing these glasses while watching the city’s east station. There is a camera mounted over the left eye and the glasses are connected to a smartphone-like handheld device.
