Stop that this minute!

Apparently we're not only going to be observed by CCTV cameras, but the future is that we're going to be harangued by them as well. A pilot scheme in Middlesbrough where cameras have been linked to loudspeakers so that those observed misbehaving can be told to stop has proved so successful that it is to be rolled out into other areas. Are you watching up there, Mr. Orwell?
