Security Cameras to Invade Manhattan

"New York is already a heavily policed city, with 35,000 officers and a counterterrorism bureau -- the first of its kind in the country -- partnering the FBI.

But Saturday's failed terrorist bomb in the Times Square tourist hot spot has provided the authorities with a new argument for expanding a sometimes controversial security blanket of cameras, sensors and analytical software."

A system of security cameras is already installed in Lower Manhattan. This was based on the London model, where security cameras are scattered throughout the city.
