The only "sense" you need is to look away from the "the law," other than "the law of the jungle." She skates.
From everything that I hear - and I used to work for the Bureau - the agents working these investigations are just waiting to see what DOJ and the White House are going to do. You can count on some major leaks if the Bureau recommends indictments and DOJ takes no action.
What has Comey and the Bureau’s leadership absolutely incensed right now is the comments coming from Josh Earnest and the White House regarding the direction of the investigation. If I may paraphrase; “...we’ve been told that the secretary isn’t really a target” and “...we’ve been told that the investigation is not indicating a possible indictment of the secretary.” Now that Obama has shown up as a recipient of some of those emails - after he denied knowledge of Hillary’s private server - the Bureau would have a little more leverage...
I'm not being sarcastic here, but you are missing something big.
The US is a third world banana republic with (for the time being) higher living standards. The rule of law began to be dismantled in Slick Willie's first term. There is no rule of law now. I mean that to be taken literally. The law is what those in power want it to be at any given moment. The "law" is written by unelected bureaucrats appointed by lawless members of the executive branch. American citizens are fined, jailed and property confiscated based on these "laws" that were never passed by a legally elected legislature.
These unconstitutional "laws" are being upheld by judicial hacks and cronies appointed for life by the lawless executive branch and confirmed by collaborators in the US congress pretending to be an "opposition party".
We have reached the point where Obama and his DOJ no longer even feel the need to put forth some mealy mouthed excuse when they violate or refuse to enforce the law. They just do & and dare the rest of us to do something about it.
That's why it is very easy to see why she will not be indicted or convicted or punished.
