NSA surveillance metadata: The government, not private companies, should store it.

Concise formulation from Schneier: "This question is much bigger than the NSA. There are going to be data—medical data, movement data, transactional data—that are both valuable to us all in aggregate and private to us individually. And in every one of those instances, we’re going to be faced with the same question: How do we extract that societal value, while at the same protecting its personal nature?"
