Did your post have to go through some sort of internal review before you were allowed to publish it? I find it weird that you're allowed to blog, let alone blog about the NSA.
I flagged it for my to-read list for after work. I'm an idiot and didn't RTFA.
This essay was deemed UNCLASSIFIED and approved for public release by the NSA's office of Pre-Publication Review on 11/21/2013 (PP 14-0081).
