They are likely butthurt that he called attention to the crying guy. Tyrants don’t like being made fun of.
No it is because they say the judge permitted a witness to remain in the courtroom while others testified, but he later forgot and admonished them for doing it. It appears the judge admitted his mistake and told the jurors to ignore his comments. I’m not certain of the effect of the formal complaint. Unless they want a mistrial or to remove the judge, I don’t think the prosecutors can do much except finish their case and hope for a conviction. My guess is they are preparing in case they want to move for a mistrial. However I think that is unlikely. They may also seek additional jury instructions to further correct the mistake.
They’re used to getting their way in courtrooms that are aligned with their objectives. Now, they actually have to be competent lawyers and they ain’t liking it.
Typical liberal, petulant children.
