But the language and meaning of the slides are in question, not the authenticity. Only 4 (or is it 5 now?) slides have been shown. The language in the slides is imprecise, because they look like slides that were used for an overview of the program, to an audience that we don't know because we haven't seen the rest of the slides.

For God's sake, Facebook was spelled wrong, or rather, whoever put the slides together didn't even take the time to properly word-wrap things. So is it really beyond the realm of speculation that some of the key phrasing was off-the-cuff, in the way that PP slides often are because the presenter plans to elaborate during the actual presentation?

And if you're thinking: well, this is the NSA, surely an organization of their import would have a crack team of slide preparers who are at the top of their game in communication...well, as Edward Tufte would kindly point out, the top people in an organization can't be counted on to prepare accurate PowerPoint slides after a fucking space shuttle blows up: http://www.edwardtufte.com/bboard/q-and-a-fetch-msg?msg_id=0...

edit: made it clear that the language and assertions of the slides were in question, not the slides authenticity.
