ABSTRACT
Two technological changes have changed policing. First, cyberspace has become pervasive not just to communicate but to act, including to carry out crimes. Second, data analytics makes it possible to discover knowledge in large data in a scalable way. There are new crimes whose target is cyberspace - destruction of online content, extortion such as ransomware, theft of online data, and global sales of illegal products. There are crimes that happen in a new way because of cyberspace - scams, spam, financial crime, and child exploitation. There are conventional crimes that happen with unprecedented scale and speed - disseminating hatred and stalking. But data about criminal activities can also be collected with scale and speed, and data analytics makes it possible to detect and understand these activities. Cyberspace also enables sharing, easily for criminals, but with more difficulty for law enforcement because they inevitably work in regulatory silos. The landscape of crime is changing rapidly and law enforcement must respond with intentionality.
