The government (Emperor in this case) is caught in the unenviable position of having to enforce stupid regulations. You're all amazed, I know.
The given: the information was classified (how high, IDK). There is an EO (don't remember the number, Google it if you are interested) that says no matter how public classified docs become, they are still classified until legally declassified (or is it unclassified?). So, even though you kind find classified docs in the public domain, they are still classified, and anyone involved in putting it out there "violated" the declassification procedure.
Now, what makes this even more ridiculous is that quite a few people who have read the Wikileaks disclosures (I haven't) poo-poo the secret nature of the documents.
So, the government is placed in the position of enforcing the classified documents even though they're not considered "secret" information by many people.
Makes the government look pretty bad. And it should.
