You seem to think I have a problem with CCTV itself. I don't. As with armed police, I recognise that it can help in enforcing the law, but fear its misuse. I'd be much happier if I could be confident that the people watching were possessed of fully-functioning brains and senses of responsibility. Only last month two men were jailed for using CCTV to spy on a woman in her flat. And a few years ago a man was publicly branded a criminal, arrested and suspended from his job because he was caught on camera taking out money from a cashpoint around the time that a stolen credit card was used in it. CCTV wasn't the problem - a failure by the police to use the information sensibly was.

And I generally approve of speed cameras as well.
