Hello, I was away for the summer. It seems that there has been some activity. If you’re here because you heard about my The FBI Has Not Been Here signs, here is a link to the page where I first mentioned them, back in 2005 or so [ETA: Internet Archive says 2002, thanks Frank]. Back when this idea was getting batted around it was originally because the USA PATRIOT Act was concerning people, the idea that if you even got a National Security Letter not only would it compel you to turn over records, but it also prevented you from telling anyone other than your legal counsel. This sort of sucked and so people fought back. Most notably the people from Library Connection in Connecticut who got the gag order part of the USA PATRIOT Act declared unconstitutional. And you may have read about Brewster Kahle talking in the New Yorker about what it’s like to get a National Security Letter. Brewster is one of the strongest advocate for the right to privacy (and libraries’ right to defend their patrons’ privacy) and even he was sort of freaked out by this. Now that we’re looking into the face of the NSA looking into damned near everything and their heavy-handed tactics to get corporations to comply with them, it’s almost quaint thinking that we were just afraid of the USA PATRIOT Act. You can read more about the idea of “warrant canaries” here. I certainly didn’t think them up, just got a little traction with this one. Oh hey look there is this image over on Wikipedia’s warrant canary article. That’s nice.
