If they get to the bottom of it and there are no indictments, they will all look like fools. Better to just let it go if no charges are going to be filed, otherwise you’re telling the world they broke the law but it doesn’t matter because the law does not apply to them.
You mean we might have a lower opinion of gov't than we already do? If there are no indictments, they will come up with some excuse - the already did for the Comey Report - "it was a weak case", "just wait for the really big FISA case coming later..."
