Everybody's friends over at the TSA had a nice fail at some point when they posted a redacted version of their "Aviation Security Screening Management Standard Operating Procedures" on their web site. Unfortunately for them, redacting by drawing boxes over the text and images in Acrobat doesn't really do anything useful, the content is still there. It took a few months before someone noticed, but once that happened the Internet took hold and the great guys over at Cryptome stripped all the censoring, replacing it with red boxes to clearly mark what the TSA considers "sensitive" and posted the result on their web site. I'm also mirroring the same here. I've skimmed the whole manual and read the censored parts in their entirety, I honestly can't figure out why they even felt the need to censor. Governments should be open unless they can provide good reason not to be, not closed by default.
