Law enforcement has been using technology to solve crimes for more than a century. Using technology to prevent crimes, however, is a relatively new idea. The movie Minority Report famously depicts a futuristic society in which police officers arrest people before they commit crimes. It’s a deeply disturbing movie with a not-too-subtle message about the danger of relying too heavily on technology.
Nevertheless, a small industry has emerged around the practice of predictive policing. New York, Chicago, Los Angeles, New Orleans and other cities have experimented with predictive policing programs. The experiments have been inconclusive and controversial.
