The NSA documents Edward Snowden leaked have sparked a debate within the US about surveillance. While Americans understood that the US government was likely intercepting telephone and social media data from terrorism suspects, it’s been an uncomfortable discovery that the US collected massive sets of email and telephone data from Americans and non-Americans who aren’t suspected of any crimes. These revelations add context to other discoveries of surveillance in post 9-11 America, including the Mail Isolation Control and Tracking program, which scans the outside of all paper mail sent in the US and stores it for later analysis. (The Smoking Gun reported on the program early last month – I hadn’t heard of it until the Times report today.)
The Obama administration and supporters have responded to criticism of these programs by assuring Americans that the information collected is “metadata”, information on who is talking to whom, not the substance of conversations. As Senator Dianne Feinstein put it, “This is just metadata. There is no content involved.” By analyzing the metadata, officials claim, they can identify potential suspects then seek judicial permission to access the content directly. Nothing to worry about. You’re not being spied on by your government – they’re just monitoring the metadata.
