Mark Mazzetti, writing for The New York Times:
One night in 1971, files were stolen from an F.B.I. office near Philadelphia. They proved that the bureau was spying on thousands of Americans. The case was unsolved, until now.
I think there are some major differences between this story and what Eddie Snowden did, but it seems like an appropriate (almost too good to be a coincidence, even) time to hear it.
