At the center of the Mueller investigation is the Christopher Steele "Russia Dossier" that was used to initiate the Trump/Russia FBI and DOJ investigation.

Steele was fired by the FBI, and considered unreliable and partisan. In the last week, it has come to light that British MI-6 intelligence also considers Steele unreliable, and in the post-2016 election transition period, MI-6 sent a letter to both the Obama administration and to the Trump transition team that Steele was unreliable.

But despite that, Steele's "Russia Dossier" was peddled within the FBI and DOJ as fact, and by all appearances was the sole documented evidence used to file FISA surveillance warrants to spy on Carter Page and other Trump officials. (100% of the "evidence", except for two partisan-written articles, both also sourced from the Russia Dossier itself)
Despite that Comey told Trump privately on Jan 6, 2017 the Russia Dossier is "salacious" and "unreliable", it had been used in recent months as false evidence to submit *four* FISA surveillance warrants on Carter Page, despite that they knew with the very first warrant the Russia Dossier evidence was false.

I'm still wondering where the FISA judges are, who should be expressing outrage that they were deceived with false evidence, and should be demanding all that fruit of the poisoned tree be thrown out of court, and any resulting convictions overturned. The longer these judges remain silent, the more convinced I am that they are also Clinton deep state agents helping to break the law.
We already know from Strzok and Page's text messages that Strzok is a friend of one FISA judge Rudolf Contreras, and that they plotted to meet Contreras ex parte at a meeting hidden inside a dinner party social event, to illegally transact their agenda secretly.

That the Mueller report barely mentions:
* Christopher Steele and the Russia Dossier,
* That the Clinton campaign and DNC commissioned and funded the Russia Dossier
* that the Russia Dossier information came directly from Russian state agents paid by the Clinton campaign,
* How Nellie Ohr and Bruce Ohr funneled this "salacious/unreliable" document into the FBI and DOJ through backchannels despite its being discredited used it as the basis for FISA warrants, and
* everyone at the top of FBI/DOJ knew Steele had been fired, and
* even Deputy Assistant Secretary of State Kathleen Kavalec on Oct. 11, 2016 had warned DOJ and FBI in a letter that Steele was an unreliaable partisan, a letter apparently buried by these deep staters in FBI and DOJ.

...that the Mueller report selectively omits all these facts further shatters the credibility of its findings.
