If you wear clothes, use passwords, close doors, use envelopes, or sometimes speak softly, then you do have something to hide; you’re just having trouble understanding that you already do care about privacy. Here are some references to help you understand why everyone, especially honest hard-working people, needs privacy.

• Techdirt – If You’ve Got Nothing To Hide, You’ve Actually Got Plenty To Hide – The line “if you’ve got nothing to hide, you have nothing to worry about” is used all too often in defending surveillance overreach. It’s been debunked countless times in the past, but with the line being trotted out frequently in response to the NSA revelations, it’s time for yet another debunking, and there are two good ones that were recently published.

• PRISM: Why You Should Care, Even If You “Have Nothing To Hide” – And, no, most of us don’t have anything to hide. In fact, the vast majority of us will never do anything the government cares about. But that’s not why you should care about your privacy.
