Re the autopsy, follow the science, Jeff. Clinical facts count more than the spasmodic emotions that your team has been selling.The testimony is certainly not a distraction.
The autopsy report by the city examiner is only one piece of evidence and he isn't Moses bringing the 10 commandments to the people.
The jurors will have weigh all the evidence to decide what killed Floyd and if the Chavin is responsible at least in part for his death and if he acted maliciously or recklessly.
You are acting that it is a done deal that Floyd died of a drug overdose but the prosecution has brought compelling evidence this isn't the case.
The prosecution's evidence is only compelling to those like you who have a political or ideological reason to find it compelling. You and your friends bought into the narrative on Day One and aren't psychologically or intellectually equipped at this late date to let it go.
To everyone else, however, it should raise reasonable doubt. The only question is whether politics, ideology, and fear will trump reason, facts, and science. Chauvin's fate rests on the answer to that question, which is why he's likely screwed.
