Cameras in UK for Toll Enforcement

cosyne writes "Saw this story on BBC News about charging people £5 per day to drive in central London. The interesting part: they plan to use surveillance cameras to snap liscence plates and compare to a database of people who paid. That's the same as stopping terrorism, right?" We mentioned this issue in an earlier story. It's an interesting challenge: the UK authorities have a problem (too much traffic in London) which is not susceptible to the usual solution (too many ways into London, can't put tolls on all of them) and so they're looking for new solutions - except most of the possible solutions are privacy-invasive in one way or another.
