After gaining access to that data—the FBI asked anyone in the area of Monday's bombing to turn over photographs and video—it falls to weary investigators to analyze that footage, from all directions at once, in search of a common thread. Somewhere inside Boston's amateur footage and CCTV video (there are 600 CCTV cameras covering the subway system alone), the FBI managed to point at the two men now thought to be the perpetrators.
But as authorities have discovered during more than a decade of urban terrorist attacks, scouring through what is thought to be the thousands of hours of video taken in the minutes surrounding any incident is a logistical nightmare. But that could change with CoSync, a piece of software under development, it turns out, at an MIT lab not far where one of the suspects shot and killed a campus police officer Thursday night.
