Bellovin, Blaze, Diffie, Landau, Neumann, and Rexford:

Architecture matters a lot, and in subtle ways.

Tim O'Reilly:

We need to move away from a Maginot-line like approach where we try to put up walls to keep information from leaking out, and instead assume that most things that used to be private are now knowable via various forms of data mining. Once we do that, we start to engage in a question of what uses are permitted, and what uses are not.

Noam Cohen's friend:

Privacy is serious. It is serious the moment the data gets collected, not the moment it is released.

Decius:

One must assume that all garbage is monitored by the state. Anything less would be a pre-9/11 mentality.

Charlie Savage:

The Federal Bureau of Investigation is giving significant new powers to its roughly 14,000 agents, allowing them more leeway to search databases, go through household trash or use surveillance teams to scrutinize the lives of people who have attracted their attention.

The manual clarifies the definition of who qualifies for extra protection as a legitimate member of the news media in the Internet era: prominent bloggers would count, but not people who have low-profile blogs.

Decius:

My blog post is not important, but it is important that people have a right to blog without worrying about receiving legal threats when they haven't done anything wrong.

Libby Purves:

There is a thrill in switching off the mobile, taking the bus to somewhere without CCTV and paying cash for your tea. You and your innocence can spend an afternoon alone together, unseen by officialdom.
