Like a vice principal in the sky, this A.I. spots fights before they happen

It's no great revelation that we live in a surveillance society. A U.S. citizen is reportedly captured on CCTV around 75 times per day. That figure is even higher elsewhere in the world. In the United Kingdom, this number is considerably greater, with your average Brit likely to be caught on surveillance cameras up to 300 times in the same period. But a lot of existing CCTV networks still rely on people to operate them.
