We can't 'know' this is false, but . . . we can look at what the implications would be if this were true.
This would require vast storage, incredible database crossreferencing, would imply certain kinds of information be available not only without warrants, but without ever needing to pull the original data. Not only would warrants be redundant, so would National Security Letters.
All without a single patriot in the government going public and blowing the lid off this, yet simultaneously putting this information in the hands of someone willing to shoot their mouth off on CNN.
Can, in theory, all this be true? Sure. It could happen. *Practically* can all this be true? No - too many conspirators have to work invisibly, never tipping their hands, never making a mistake. Just don't buy it.
