According to an article in the Guardian, where Greenwald’s original Snowden leak articles first appeared, there’s an article about Greenwald’s partner, David Miranda, appealing his 9-hour detention when transiting through London between Greenwald in Rio and Poitras in Berlin that notes Miranda was found to have a hard drive with “58,000” documents:
“The judgment stated that Miranda, a Brazilian national, was stopped in transit between Berlin and Rio de Janeiro after meeting the film-maker Laura Poitras. He had been carrying encrypted files, including an external hard drive containing 58,000 highly classified UK intelligence documents, “in order to assist the journalistic activity of Greenwald”. The Guardian made his travel reservations and paid for the trip.”
If that statement is accurate, and strangely the reference to “UK intelligence documents” seems somehow exclusionary of the US NSA docs, since UK intelligence docs would be in reference, one would guess, to the GCHQ, then I’d surmise a minimum of 58K docs to possibly up to 100k or so. Certainly not “1.7 million” in any case. I guess now people will start to ask precisely how many pages total in the documents were taken… urgh.
