About a day later, photographs of four suspects were broadcast on television. Their images had been captured on surveillance cameras near the sites of the attempted attacks.
The remarkable speed of that investigation was repeated in June this year when terrorists attempted to detonate two car bombs in London.
Aided by surveillance cameras, British investigators began unraveling the plot later that day and tracked the suspects to Glasgow, Scotland. Several suspects were soon arrested.
Police officials credited the "Ring of Steel" -- a network of thousands of surveillance cameras that line London's intersections and neighborhoods -- for providing license plate numbers, suspects' image and other important clues in investigations.
New York City, specifically lower Manhattan, the site of two terror attacks, will have a similar system in place by the decade's end if it gets the needed funding.
