The trend began in Britain a decade ago, in the city of King's Lynn, where sixty remote controlled video cameras were installed to scan known “trouble spots,” reporting directly to police headquarters. The resulting reduction in street crime exceeded all predictions; in or near zones covered by surveillance, it dropped to one seventieth of the former amount. The savings in patrol costs alone paid for the equipment in a few months. Dozens of cities and towns soon followed the example of King's Lynn. Glasgow, Scotland reported a 68% drop in citywide crime, while police in Newcastle fingered over 1500 perpetrators with taped evidence. (All but seven pleaded guilty, and those seven were later convicted.) In May 1997, a thousand Newcastle soccer fans rampaged through downtown streets. Detectives studying the video reels picked out 152 faces and published eighty photos in local newspapers. In days, all were identified.
