New documents provided to journalist Glenn Greenwald by NSA leaker Edward Snowden show that a British intelligence agency has been manipulating the internet.
Greenwald's new site, "The Intercept," reports that the British spy agency Government Communication Headquarters (GCHQ) has developed a suite of covert tools to manipulate internet content and usage.
Ranging from tools to change the outcome of online polls, to artificially increasing website traffic, this startling report questions whether the GCHQ may be blurring the line between online surveillance and state propaganda.
The revelations come as hearings begin in the United Kingdom to determine whether the GCHQ's mass surveillance programs violate human rights. The British Parliament also plans to debate a new law that would expand the government's reach into internet activity.
To help us understand this new leak and what it means for internet users in the U.K. and around the globe, we turn to Julia Angwin, an investigative reporter at ProPublica and author of "Dragnet Nation: A Quest for Privacy, Security and Freedom in a World of Relentless Surveillance."
