Ahmad Rahami's Capture: More Than 8,000 Cameras Helped Snare Bomb Suspect

The black-and-white image that caught Ahmad Khan Rahami near the site of a Manhattan explosion Saturday night and helped investigators identify him as a bombing suspect comes from one of more than 8,000 cameras added to New York streets since the September 11 terror attacks as part of the city's "Ring of Steel."

The number of cameras in New York City has been growing steadily in the 15 years since the attack on the World Trade Center in Lower Manhattan as law enforcement's ability to monitor the city has grown ever more sophisticated.

"That's the world we're living in now. Any street, any incident in New York City you get to -- most of the time -- that gets captured on video surveillance," New York City Police Commissioner James O'Neill said at a press conference on Monday.
