«There are about 2.5 million CCTV cameras in Britain, 10% of the worldwide total. An unknown number of them, in unknown places, are being hooked up to a computerised facial recognition system which, on the available evidence, doesn't work. This might seem absurd, rather than sinister, where it not for the fact that the process is being carried on either in secrecy or, as in Newham, behind a blare of publicity which conceals the lack of real information about how well the system works. You have been warned. But you haven't been told. Smile!»
And by the way, Big Brother is watching you. Honest.
