@Cruiser a couple of things to consider:
You seem to be trying to justify what Flynn did or at least obfuscate the facts by focusing on how the US public learned of his actions and not what he actually did. Blaming a low level operative in the intelligence community for this is like trying to pin the entire embarrassing episode of torture and abuse at Abu Ghraib on Lynndie England while letting Rumsfeld walk free with not even a slap on the wrist.
The Trump admin was given warnings over a month ago that there could be problems brewing and an investigation was under way. Even knowing this Flynn was still briefed with classified information and relied upon to make decisions for the administration. You would think that, with the foreknowledge, his activities would have been curtailed and responsibilities reduced but they were not. As far as I can discern no concern was registered, nothing was done about it and it appeared that the present administration was going to be swept under the mat.
It appears that even though the administration knew there was an investigation and potential problems, the VP Pence (and we should still address the lies of Conway and Spicer) still went before the US public and said Flynn did not do what he has been shown to have done. Again, he knew there were questions and yet felt he could do so with impunity. Was it because he did not think Flynn would be found to have misled them or is it because he felt like any conflicts of interest could and would just “disappear”? Was he not informed? Did he know and lie? Was he in on it from the start and covering his own ass? All questions that need to be investigated. What are the odds that Flynn was operating in a vacuum with none of the big boys like Trump and Pence being aware of, if not authorizing, his discussions with the Russians? Since Trump is a micro-manager probably pretty slim.
This morning, now that he has resigned, he mentions “several” phone calls he had with the Russians, not just one as he, and Pence, had earlier stated occurred. More lies upon lies. How can we trust them Ok, I admit I never did but how can his supporters continue to do so?
The fact that he, Flynn, colluded with another country that does not have our best interest at heart and either conveniently forgot or flat out lied about it seems, in my opinion, much more dangerous to our national security than someone pointing out that he did it. An open society has inherent dangers but I would rather live in one where people like this and Snowden point out the underhandedness of our government officials rather than let them continue to get away with it.
