Toss the guy who didn’t show up.
The guy who didn’t show up, Juror 4, was being challenged by the prosecutor. He should be kept. Unfortunately it appears each side only has 10 peremptory challenges, so the prosecutor is trying to get rid of him for cause (unlimited number can be challenged if there is cause). Prosecutors will be found by this judge to justify for cause everyone they challenge. Judge won’t treat Trump the same. He’ll say the cause isn’t sufficient and make Trump burn up his challenges. Jury will be stacked.
