Do yourself a favor and really go back and read through the decoding of Q's very specific posts about Mueller.  Q says "Mueller working off U1".  What does that mean to you?  That means a plea deal.  In exchange for helping Sessions/Huber quickly locate where all the bodies are buried (by singing), Mueller negotiated a pardon for himself in Nov 2016, long before he was appointed Spec Counsel. THIS is how he is working off his forced involvement in the U1 deal and no doubt other horrible things.  You have to remember, Mueller was a marine, and like many people he went to D.C. thinking he was doing his patriotic duty, and then in the swamp he got severely blackmailed and was forced to do the DS's dirty bidding.  It happened to so many. All the stuff with manafort, flynn, and now stone is theater.  It had to look good to the DS that Mueller was still on their team.  Once these DS guys are locked up (or executed), all these people will be pardoned and their fortunes restored to them for playing their parts like true heroes!
