ACLU summary of NSA surveillance actiivty

I have not posted anything on Edward Snowden or the activity of the NSA, because so many others are doing so; however, I have found a relatively concise summary of the NSA surveillance activity with links to many supporting resources. It is a good way to catch up with the story.

Note that it was published by the American Civil Liberties Union, so focuses on violation of privacy guarantees. I would love to see a similar summary with supporting resources that is focused on positive outcomes as a result of NSA surveillance.
