The New Yorker: How to Conduct an Open-Source Investigation, According to the Founder of Bellingcat. “On a recent afternoon in central London, twelve people sat in a hotel conference room trying to figure out the exact latitude and longitude at which the actress Sharon Stone once posed for a photo in front of the Taj Mahal. Among them were two reporters, a human-rights lawyer, and researchers and analysts in the fields of international conflict, forensic science, online extremism, and computer security. They had each paid around twenty-four hundred dollars to join a five-day workshop led by Eliot Higgins, the founder of the open-source investigation Web site Bellingcat. Higgins had chosen this Sharon Stone photo because the photographer was standing on a raised terrace, which makes the angles confusing, and used a lens that makes Stone appear closer to the Taj than she actually was. The participants, working on laptops, compared the trees and paths visible in the photo to their correlates on Google Earth.”
