The 2nd part of Muller's report was about Obstruction of Justice: attempts to create false evidence, limit the investigation, witness tampering and intimidation. "But for the OLC memo..." Trump would be charged, prosecuted, and likely convicted.
I'm not sure if/how that memo applies to state prosecutions for crimes like bank fraud, insurance fraud, or money laundering. But if Trump puts his thumb on the scale and tries to use his position to make those investigations go away, that's not just Obstruction of Justice but Abuse of Power.
You have not. The "summary" is not that—it is deliberately misleading, and contains almost none of the information in the report apart from a few incomplete sentences. If you are interested in accuracy—let alone justice, and I realize both are big ifs—you can and should read analyses of the (redacted) report itself, eg. on Lawfare, JustSecurity etc, where they have gone through it in detail. Barr has repeatedly lied about the report and about Mueller's reasoning—that much is clear from what we know; to be satisfied with his inaccurate description of the investigation is just laughable.
"One day, we shall die. All the other days, we shall live."
Mueller would not "surely" condemn Barr in public. He has nevertheless made several statements that directly contradict Barr's claims about the report and about the team's reasoning, in addition to the written objection he sent Barr. Surely you—an intelligent and literate man concerned with truth and criminal justice—are aware of the extensive reporting on these matters?
"One day, we shall die. All the other days, we shall live."
Why would you use this extremely roundabout way to find out whether the Barr letter accurately represents the Mueller report, when both are available on the internet and you can just compare what they say?
He's misleading about Russia and outright misrepresents about obstruction of justice.
