The woman was still convicted, the jury ignored him on that and he did recuse himself later so all was not lost.
He still needs to get out of that business. Unless it’s proven he had a medical condition that day that was caused by something preventable in the future, he should be considered insane and not eligible to judge the sanity and actions of others.
But really good to know that ordinary citizens can recognize insanity and act accordingly. I would have doubted that today.
