these jurors are lay people. They don't know the legal standards. To me, once this issue surfaced, the jurors should have been questioned about this juror. Just like they got questioned when Nurmi thinks they did something wrong. It's pretty normal for jurors to be questioned in chambers going by this trial.
Whatever notes came out should have been seen by counsel too. I would love to hear from Juan on this. To me, if the jury send out an indication of a serious problem, the judge is obligated to investigate whether or not the jury uses the proper legal description in the note. I really want to hear more about what went on and how it was dealt with. But this sounds funky to me. If a jury wants someone off right from the beginning then it should be fully investigated and followed up on later in the case of allegations that a juror is not deliberating in good faith or bringing in outside info etc.
