One of the key points that officials have been making in defense of the NSA surveillance is this idea that even if they‘re collecting all this data on your communications, they can‘t actually do anything with it, because they keep it safely locked up in a lockbox, and only check it if they have some bit of data they want to find out about later. That was the crux of the claims made by former NSA/CIA boss Michael Hayden who seemed to think that „data mining“ and „asking the database questions“ were two different things. However, as William Saletan is pointing out at Slate, the lockbox is a lie.
