what is interesting is that were originally thought to be a trump favorable juror, but it turns out they were a left-wing nut job with a history of tearing down republican campaign signs.
the nice thing as the defendant you can investigate all these jurors and if you find something you can report it anonymously to the prosecution and they are bound by law to bring the information to the judge. Which might be exactly what happened here.
It is a round about way of the defense to excluded people it doesn’t want without having to waste one of it’s official cuts.
