I haven't followed the trial closely, so I can't answer your question. But no, in his opening statement, the prosecutor, an African American man of notably even temperament, specifically told the jury that they should NOT treat this case as, in effect, a symptom of a larger American race problem, but should listen to the evidence and the case the state presented and judge it on the merits.
We may safely assume that if there was any overt evidence for Chauvin being a racist, as there is, for example, in the case of Ahmaud Arbery's killers, it would be all over the news, and the prosecution would surely use it. (N-word texts, etc.) But I don't believe there is any evidence of that sort. I'm sure Armstronglivs would know.
There is, of course, the overhanging sense among many that Chauvin simply wouldn't have treated a white male perp of similar size and behavior (i.e., resisting arrest a few minutes earlier) in the same way, and that that presumed differential, in and of itself, is a manifestation of racist predisposition and intent. I'm somewhat persuaded by this. As I've argued earlier, this feels to me like so-called depraved-heart murder: somebody (Chauvin) whose behavior evidence such callous disregard for human life that even if he didn't premeditate Floyd's death when he first set that knee on his neck, he is responsible for that death.
In his 18 years on the MPD, Chauvin had approximately one complaint for excessive force per year. That's being excluded from the trial. But it suggests a guy with a problem.
