I am not clear as to whether the jurors were allowed to take their notebooks into deliberations.
Not to butt in your conversation but I was watching after the judge gave the jury their instructions and when they left the trial room and went into the room for deliberations.
Someone off camera told the judge that several jurors left their notebooks (including at least one of the alternates). The judge then had that person gather them up, told him/her to take them to the jurors they belonged to and to lock up the alternates notebooks.
I was very curious about it which is why I was still watching to see what would become of those notebooks.
