Even as debates continue about pervasive government monitoring of our lives, surveillance technology is becoming more sophisticated and pervasive. New York City residents in just three boroughs live and work under the watchful gaze of over 15,000 cameras. "Thousands of volunteers from around the world participated in the investigation, tagging 15,280 surveillance cameras at intersections across Manhattan (3,590), Brooklyn (8,220) and the Bronx (3,470)." Police identified him through facial recognition technology that compared his image at the protest against photos on his Instagram account. Those numbers also don't include agencies making use of competing surveillance tools or systems they themselves have developed.
