Au contraire, they certainly want the cluefull to be afraid
To the contrary, they are targeting both sides. They want the people who understand the truth to know that the truth will be discredited just as easily as lies can be propagated.
Then again, I think the truth here is that Snowden is also a patsy of the sincere sort. I'm sure their anti-spook spooks detected him as a possible security risk and almost as sure that he was fed the information they wanted to be leaked. Ask Michael Hastings if you don't believe me. Oh wait, his car was hacked and used to kill him. Oh wait, it was just another amazing accident.
