There are a few interesting anecdotes about this huge story - This is the same leak that Glenn Greenwald describes to Edward Snowden in Moscow (-> -> -> -> POTUS), meaning this story has been in the making for at least 1.5 years. Second, this quality and quantity of leaks is incredible and can only be attributed to a news organization that takes security as a paramount consideration, setting up proper secure channels…
Are you sure these are the same documents/from the same source? (As far as I recall, those were from a drone pilot, that's done a few tv appearances already?). Or that was my impression, anyway. [Bad form to comment before I've read the story, but just wanted a clarification - if this was an assumption or something that's been stated clearly by one of the people involved?]
I also recall Laura Poitras mentioning the work that Jeremy Scahill was doing on this topic at one of the Q&A's she did.
