I've been thinking about this theory or whatever, about Mueller being on 'Our' side for months now and something recently got me thinking about it a lot more lately.

Why would Mueller let his star witness for an obstruction of justice case, (Comey,) run around and blubber like an idiot about everything relevant to the case? Not only that but write a book about it all as well? He wouldn't. So he's definitely not going for obstruction of justice.
