As I've said in the past, we should all be concerned about privacy even if you're not doing anything wrong.
Bruce Schneier made this point last week in discussing the value of privacy: "Widespread police surveillance is the very definition of a police state. And that's why we should champion privacy even when we have nothing to hide." Jack Balkin also discusses the dangers of a national surveillance state (via).
Wired Magazine published documents (pdf) from the EFF's suit against AT&T . These documents are currently sealed because AT&T claims the documents contain proprietary information, but Wired believes the public's right to know the full facts in this case outweighs AT&T's claims to secrecy. A chilling read.
It's ironic that in order to protect our society, we are relinquishing the very liberties that supposedly define it.
