After the attempted bombing in New York's Times Square just over a month ago, no one can be in any doubt of the significance of video surveillance systems. Within hours of the car being discovered, police had used surveillance camera footage in a nearby shop to identify a suspicious looking man seen near the vehicle.
In the London bombings in July 2005, where 52 were killed and 700 wounded, police officials were able to trace almost the entire journey of the four bombers as they prepared for the attacks, on dozens of surveillance cameras placed on the streets, and in railway and tube stations.
It's not just terrorism, for crime too, police today turn immediately to surveillance cameras to try to discover what took place." (source)
