They are not about justice but revenge. I think the evidence will prove that Chauvin did not murder floyd but in fact was the massive amount of drugs in his system causing him to overdose and die.
But blm will never be appeased. If by some terrible happenstance the jury find chauvin guilty of murder. Blm will riot because "there's a system in place that is objectively racist" and if chauvin walks ( which is likely) they will riot because "there's a system in place that is objectively racist"
The fact some higher ups in blm said if they don't get the verdict we want "their will be hell to pay" is very telling about what blm is really all about..and its not about black lives matter.
