Future Tense is a partnership of Slate, New America, and Arizona State University that examines emerging technologies, public policy, and society. Police in China have nabbed three fugitives using facial-recognition technology at a series of concerts in Eastern China, the Wall Street Journal reports. Police have employed the surveillance tool over the past two months at performances by Hong Kong pop star Jacky Cheung, also known by his nicknames "God of Songs" and, more recently, "The Nemesis of Fugitives." In one case, police were able to use a facial-recognition system to identify a 31-year-old man in a crowd of 60,000 concertgoers, according to state media. In another, the technology recognized a man who allegedly failed to pay for $17,000 worth of potatoes in 2015 and had since then been living under a pseudonym.
