Recent news reports claim that the City of Boston tested an IBM video mass surveillance system at the Boston Calling Music Festival last year.
 
According to a local blog, Dig Boston, a new, sophisticated event monitoring platform was deployed and evaluated which gave authorities “a live and detailed birdseye view of concertgoers, pedestrians and vehicles in the vicinity” of the event. Using IBM’s Smarter Cities solution, the City of Boston leveraged its existing camera infrastructure to monitor everyone who attended the music festival.
