Names like Snowden, Manning, Kiriakou or John Stockwell, William Binning and Thomas Drake (both of NSA whistleblower fame) are well-known, especially in independent and alternative media circles. 

But lesser known are the names of those abruptly fired and dismissed from their posts as analysts or as officers for merely questioning and pushing back in real time against what they understood to be disastrous and criminal foreign action and policy. We suspect that this list of names, still largely unknown to the public or media, is much bigger than anyone knows. Such ex-employees of the CIA, NSA, DIA or other alphabet soup agencies typically have their security clearances revoked and are threatened with criminal prosecution should they ever reveal state secrets and classified information. The possibility of future employment even in the civilian world then comes under threat. This means most of them remain unknown.
