Cameras at traffic lights

THE EDITOR: There is a new invention called a video camera. It can run by itself, if plugged in and turned on and will record on something called a video tape all activity in a given area. Almost every airport in the world has them in operation for two main reasons. One, to spot baggage handlers who steal people’s luggage, and, two, to protect innocent travellers from drug traffickers who place things in one’s luggage for later collection at the point of disembarkation. But like breathalysers, digital cameras at traffic lights, radar guns and such hi-tech equipment, they are beyond our technical ability. By 2020, we should have these things in place.
