un-be-lievable.
It's perfectly believable, and was done previously for the Manning/Wikileaks incident.
The Guardian and Washington Post are posting Top Secret material. You're not allowed to have Top Secret material on a government or military unclassified computer. If you do, the leakage has to be reported, and the computer has to be scrubbed. Material isn't automatically "declassified" simply because it was leaked to the media.
There's a vast collection of idiots in the media mis-reporting the story, which is being amplified by idiots on FR.
