NSA spying on Americans' Facebook profiles

NSA spying on Americans' Facebook profiles:

The US National Security Agency has been spying on the social media profiles of an unknown number of users, including US citizens, since 2010 in what it calls an effort to "discover and track" connections between Americans and suspected terrorists.

The New York Times reported Sunday that the latest revelation of NSA spying on Americans comes via documents provided to the paper by former NSA whistleblower Edward Snowden, who is wanted by the United States on espionage charges and is currently living in exile in Russia.
