Photos: Video cameras keep watch in London

Five cameras--these are in London, in a photo from July 2000--can see better than just one. As far back as 1999, it was estimated that a typical person in the U.K.'s capital could expect to be caught on film an average of once every 5 minutes. By one recent count, there are approximately 10,000 state-funded CCTV cameras in London today.
