The latest disclosures from the leaks of Edward Snowden show the National Security Agency is mapping out the social media connections of an unknown number of American targets. Using phone metadata and online activity, the NSA has created intricate graphs showing an individual’s social networking and extensive personal information including whereabouts, religious or political activity, and private behavior. The mapping has been in effect since 2010, when the NSA lifted restrictions that barred the targeting of Americans. The NSA says the aim is to uncover ties between Americans and foreign terror suspects.
