Here's my lukewarm take. The judge knows if there's a mistrial there are riots and whether or not he admits it even to himself, that's influenced the proceedings. However, he's literally noted on the record multiple grounds for mistrial, while still not granting any motions actually to call one. So his own statements on the record support an appeal.
Riots are a lot less likely about an appeal because nobody gives a shit about appeals courts. There aren't days of oral arguments or much drama at all. Stuff is mostly decided on paper. Mobs of retards don't read. They watch TV. So without compelling visuals, a reversal on appeal is a lot less likely to have extreme riots. You'll just get a minor chimpout.
