For too long, the field of privacy has been becalmed by religious fealty to a concept propounded by two New England aristocrats who were annoyed by paparazzi taking pictures of a party in a home. The ill-considered explosion set off by the NSA in its zeal to prevent all future acts of terror has opened up space for new thinking on the subject. An op-ed in the Washington Post is a good example: This is an anonymity problem: The NSA cannot create a dossier on you from your metadata unless it knows that you made the calls the agency is looking at. The privacy question is all about data-gathering: Should the NSA have access to nationwide metadata? The right answer to that question is yes.
