Apparently the word "collection" does not mean collection.
Asked by Wyden, “Does the NSA collect any type of data at all on millions or hundreds of millions of Americans?” Clapper replied, “Not wittingly. There are cases where they could, inadvertently perhaps collect-but not wittingly.”
Blair drew a distinction between the “collection” or mining of data on specific U.S. citizens by NSA and the massive trove of phone call information that was turned over to the NSA under a negotiated agreement among intelligence officials, the telecommunications companies and the FISA judges. The purpose of the FISA order was to store information in the event that U.S. intelligence agencies need to access it after getting specific intelligence that somebody in the U.S. might be tied to terrorism. It is only at that point, he explained, that the NSA goes back to the court to get permission to mine or “collect” the data.
