In CA, the foreperson is selected once the jury goes into the jury room to start deliberations. The point is for the jury to decide who they want to lead the discussion, not to have the state do it. I think Josh is assuming juror #1 is the foreperson, it doesn’t have to go like that.
I am surprised that they are challenging jurors like this, in CA they seat a bunch of people to fill the box and then start questioning and toss people, filling the slots with new people, until they finally have the panel. Each state does things differently though, it sounds like the jurors have to pass through selection and be seated instead of setting up a default slate…this way does slow things down though.
As for juror anonymity…in general the parties do get information about who the jurors are, but that is never to be shared publicly; the jury members can out themselves but otherwise are to be kept private. Anyone who violates that is going to jail, judges don’t mess around with that. The exception is something like a mob trial…you could argue (pretty easily) that full anonymity is required because of how Trump goes after people (and sends his goons after people), but if any juror is harmed that’s going to come back to Trump, and it’s not going to stop the trial, so I think the judge decided that direct violence is a line that Trump won’t cross here. We’ll have to wait and see if that’s correct…jurors will report if someone threatens them or their names are spread publicly, that will happen before anyone tries to attack them. Trump’s goons aren’t like the mob, they will threaten people but most are cowards who wouldn’t go through with actual violence.
