This is a stunning report...not least of which in how it continues to show the NSA's apparently shoddy IT...the PowerPoint presentations being taken are one thing, but the hundreds of thousands of pieces of surveillance data, and that's just what the Post chose to sift through.
Still, the specifics of data extraction aren't clear...are the NSA mining a data stream as they please from Facebook? Or are the Facebook transcripts, as detailed in the closing anecdote, a result of a data request in an ongoing investigation of a previously identified suspect?...which is, purportedly, the same kind of access any law enforcement agency can make.
