How do you obstruct "justice" if there was no underlying crime? Yes, I know, a dozen Russians speaking broken English had a better marketing campaign going than the multi-million dollar one Hillary had, so we indicted them for Facebook posts, but, Trump wasn't a part of that yet he and his family and his co-workers were all being investigated. Everyone knew before going into the investigation that the Trumps and the campaign did not have anything to do with the attempt at influencing the public with the Russians. So, for the useless indictments against the Russian military folk who will never, ever be served, let alone tried, and justice will never be served, it was worth the tens of millions of dollars of taxpayer money, because.....well, I'm not sure why, but it must have been.
Volume II is ideological in that is a report about something the intended reader, the AG, could do nothing. The SC could do nothing. The meaninglessness of it is astounding in that there would be no obstruction (and, clearly, there WAS no obstruction) if there was no investigation, and there was no honest foundational reason for the investigation. Fruit of the rotten tree and all that. So, there should have been no report beyond, "nothing we can do, so thanks for coming. Tip your waitresses, folks!" That there is a whole lot of confusion - exactly what Mueller was claiming to try and forestall - is a travesty. And, you paid for it. And I paid for it. And, I'm not happy with that.
