Guardian reporter: Snowden can cause US greatest harm in history
None
Glenn Grinwald, a Guardian correspondent who first interviewed the American whistleblower Edward Snowden, told an Argentinean newspaper that Snowden has enough information to cause the US the greatest damage in its history.
Greenwald noted that this is not Snowden's goal, but that he aims to expose the loss of privacy involved in using some software, without people's knowledge. (AFP)
