Possibly the craziest conspiracy-theory ever about Mueller, Trump and the Deep State:
http://dystopiausa.com/what-is-robert-mueller-up-to/
Mueller and Comey believe that the shadow government they served so long is on life support now that so much corruption is known to the masses. They believe that Trump cannot fire Mueller because he will be accused of obstruction and potentially impeached. Under this theory, the FBI bros know that there is absolutely zero evidence that Trump colluded with the Russians. Who would know better than they? Even the rabidly anti-Trump media will accept a conclusion of no collusion since Mueller has packed the investigative team with Clinton and Obama shills. By Comeys gambit of outing Loretta Lynch, he signaled to Congress that he is looking to deal his way out from under the Clintons deadly gaze. His BFF Mueller then gives Comey immunity to take down the Swamp instead, thereby saving both their necks from the gallows when the Deep State is fully exposed.
(emphasis mine)
-----------------
Mueller knows that the Deep State is going down and that there was no collusion. And he knows that his only hope is to switch sides and work for Trump now.
That means that even though Mueller is indicting associates of Trump, that's merely cover for an actual secret investigation into Clinton and the Deep State.
And this is how the mind of a Trump-supporter works.
