From front-page news stories featuring transcripts of wiretapped campaign officials to dramatic cyberattacks using hacking tools stolen from the National Security Agency, intelligence and surveillance issues have saturated the news in 2017. Yet there were also plenty of important surveillance stories that didn't get the exposure they deserved: the ongoing debate over reauthorizing the NSA's controversial section 702 spying authority, set to expire at year's end; the Supreme Court's pending consideration of Carpenter v. United States, which could radically alter the contours of Fourth Amendment law; law enforcement's growing reliance on sophisticated data mining to attempt to identify criminals or terrorists before they act. The Cato Institute's annual surveillance conference will gather prominent experts, policymakers, technologists, and civil society advocates to explore these issues and more—and debate how much monitoring we should accept in a society that aspires to be both safe and free.
