@BillW,
As I see it:
- they will argue that it was widely known that the 'rally' he attended was a protest...attended by the relatives of Floyd, with the juror wearing clothing about Chauvin's actions...surrounded by relatives who were also dressed appropriately for a Floyd protest...shows that he knew it was a protest and went dressed appropriately for the protest.
- They will argue that 'get your knees of our necks, has never been seen before Chauvin, and therefore is directly linked Chauvims actions
- They will argue that his Tshirt showed he already had a preconceived notion of Chauvin's guilt
- They will argue that his words after the trial matched what was on hi T-shirt before the trial....showing he had a preconcieved notion that all police used excessive force, and therefore had a preconceived notion of Chauvins guilt
- they will re-iterate that his attendance at the protest, dressed for the protest, surrounded by relatives dressed for a protest, the words on his T-shirt, and his words after the trial all show he had a preconceived belief in Chauvin's guilt and together, these pieces of information can't be interpretted in any other way,
- They will argue that the juror lied about having attended the rally , and that any explanation the juror provides for his attendance will be self-serving, due to his vested interest in seeing Chauvin found guilty.
As you said though Bill - facts don't change. And I don't think anyone would find Chauvin not guilty (well, maybe an incredibly small percentage of people).
