It was speculation by Barnes on Racket's stream. He said that the woman who joked about the judge not being able to tell if any of them sat on his chair was probably the foreman, because the type of juror to make a joke like that is the 'leader' type that would inevitably snatch up the foreman position. He also said she was a major threat to Kyle because she's probably one of those Yankee aristocrats that all live along the lake, one of the original settlers descendants that are basically New York liberals in the midwest. I think he was basing THAT part of speculation how she spoke to the judge (older man in position of authority that she joked around with as an equal).
I don't know if that's what the guys in this thread basing their posts on, but Barnes has got more experience in a court than me, and he's been right about the defence being stupid cunts already so I'm willing to listen to him on this too.
