Britain has taken one more step in becoming a surveillance society with this: a "crime-predicting" CCTV that seems to be plucked straight out of science fictions:

Computers are programmed to analyse the movements of people or vehicles in the camera frame. If someone is seen lurking in a particular area, the computer will send out an alarm to a CCTV operator.

The operator will then check the image and – if concerned – ring the police. The aim is to stop crimes before they are committed. If a vehicle is moving too fast or slow – indicating joyriding or kerb-crawling, for example – a similar alert could be given.

I admit I had to look up kerb crawling
