Big Brother is Catching You

London's public cameras apparently played a role in cracking the London case. Link. Excerpt:

The critical breakthrough in the hunt for the London bombers came on Monday night in a police video viewing suite.

Detectives involved in watching thousands of hours of film for glimpses of the terrorists had been given a "profile" based on a simple question posed for their guidance by senior officers.

The question was: what would the terrorists look like? The answer was that they would be young men, probably in their 20s and 30s, and they would be carrying rucksacks.

At 8pm on Monday, on footage from a camera at King's Cross station in central London, officers found images of four young men carrying bulky rucksacks, similar to those in which soldiers carry radios.

The civil libertarians who hate the new trend in American crime fighting (link) probably cringe at this, but an open society needs some sort of defense against its porousness.
