That said, it is the case that even if classified documents are openly published, if they are still classified, it is forbidden to read them (at least for mil personnel, and I know as a 2nd tier supplier I've got lots of similar rules to follow about not accessing docs I don't have a demonstrable need-to-know) .

So, if you are in that environment, and there are such docs floating around, and you want a security clearance, best to avoid reading them, and document how you did so (ya, hard to prove a negative, but contemporaneous notes, such as an email to a friend, or reporting it to authorities might work?)
