From Keith Thomas, Richmond, North Yorkshire, UK
So computer vision systems can tell innocent from suspicious behaviour (14 January, p 14)? Some years ago I ran into a town centre car park to renew a ticket, only to be forcibly apprehended by two police officers chasing a shoplifter who took cover amid the cars.
If our highly trained law enforcement officers working face-to-face can mistake an identity, how will automated systems working at a distance fare?
