How do you spot a terrorist in a crowd? A Chinese answer

[davidbfpo]

A BBC World Service report from Guiyang, a Chinese city in the south-west, with a population of over 4m and noted for its investment in big data and computing. Background and map:https://en.wikipedia.org/wiki/Guiyang

The BBC reports (5mins podcast) states:

China has been building what it calls "the world's biggest camera surveillance network". Across the country, 170 million CCTV cameras are already in place and an estimated 400 million new ones will be installed in the next three years. Many of the cameras are fitted with artificial intelligence, including facial recognition technology. The BBC's John Sudworth has been given rare access to one of the new hi-tech police control rooms.

It is a rather curious piece, complete with interviews - all reassuring, bar one - and is aimed at everyone.
