I believe that for about the first year this WAS a witch hunt, he did ruin lives for no apparent reason, I believe that Flynn's indictment was an act of blackmail and coercion on Mueller's part. But I can't help to wonder that Mueller isn't actually making a case to go after Clinton, Lynch, etc on the back end.
Thoughts?
My thought is that I seriously doubt that this is even a remote possibility.
Note; If someone were investigating me, I'd be inclined to refer to it as a "witch hunt" too....particularly if the stakes were as high as these are.
Think about this, there was a time when witch hunts were a source of perverse entertainment. People would gather 'round the burning of a supposed witch. Maybe it's human nature to deflect. How many of those folks watching were secretly telling themselves, that god it's not me at the stake.
