If you haven’t watched it yet, clear a few hours from your schedule at some point and watch the two-part Frontline special on the NSA and Edward Snowden that ran in May.
It’s called “United States of Secrets.”
Even if, like me, you think you understand the history of the NSA and the general technical aspects of what Snowden leaked, you may be surprised. Very much worth a watch.
Part 1 is stream-able via the PBS site here.
Part 2 is stream-able here.
