Well, whaddya know. According to the Obama administration, whistleblowers are now terrorists, or something.
In 2008, now President Obama ran with the following as a key plank in his campaign: Protect Whistleblowers: Often the best source of information about waste, fraud, and abuse in government...
Well, that was then, this is now. You see, he was for whistleblowers before he was against whistleblowers, which apparently makes it all right, somehow.
Yes, informing the American public of misdeeds by the US government is considered "aiding the enemies of the United States." The reality, of course, is what they're saying is that they really mean "the current government" when they refer to "the United States," and "the enemies" are the American public.
And, part of the program seems to be to put pressure on anyone to snitch on their colleagues if they suspect potential leakers. Government employees who fail to report colleagues who exhibit "high risk" behaviors may be subject to criminal charges. Basically, snitch on anyone who acts suspiciously, or else... And, of course, it's not just the Defense Department. The Agriculture Department has an online tutorial teaching people how to spot potential whistleblowers, entitled "Treason 101."
By now, you should realize how it works. Good little peons support their government. So if you're a whistleblower, then you're a terrorist. If you're critical of a government agency, you're a terrorist. If you're a supporter of civil liberties or concerned about NSA spying on American citizens, you're a terrorist. If you're a second amendment supporter, you're a terrorist.
