Glenn Greenwald is the journalist who has done the most to expose and explain the Edward Snowden files.

Glenn Greenwald was one of the first reporters to see – and write about – the Edward Snowden files, with their revelations about the United States’ extensive surveillance of private citizens. In this searing talk, Greenwald makes the case for why you need to care about privacy, even if you’re “not doing anything you need to hide.”

As one of the first journalists privy to NSA whistleblower Edward Snowden’s archives, Glenn Greenwald has a unique window into the inner workings of the NSA and Britain’s GCHQ. A vocal advocate for civil liberties in the face of growing post-9/11 authoritarianism, Greenwald was a natural outlet for Snowden, who’d admired his combative writing style in Salon and elsewhere.
