In May 2013, Glenn Greenwald set out for Hong Kong to meet a source who claimed to have astonishing evidence of pervasive government spying and insisted on communicating only through heavily encrypted channels. That source turned out to be the 29-year-old NSA contractor Edward Snowden, and his revelations about the agency’s widespread, systemic overreach proved to be some of the most explosive and consequential news in recent history, triggering a fierce debate over national security and information privacy. As the arguments rage on and the government considers various proposals for reform, it is clear that we have yet to see the full impact of Snowden’s disclosures. In April 2014, Greenwald and his colleagues at The Guardian received the Pulitzer Prize for Public Service. Don't miss Greenwald speak in-person as he fits all the pieces together, recounting his high-intensity eleven-day trip to Hong Kong, examining the broader implications of the surveillance detailed in his reporting for The Guardian, and revealing fresh information on the NSA’s unprecedented abuse of power with never-before-seen documents entrusted to him by Snowden himself.
