Think so, eh?
I believe it is SOP in any court that during the Judges Jury instruction he specifically tells them “I will tell you what the law is... you decide the facts”
Yes it is, in clear abeyance of history and SCOTUS decisions. Now while I don’t think it’s a good state of affairs that he can sit there and lie to you and not wind up in a cell the next morning with some pervert he sentenced, so what? Do you think he can climb inside your head inside the jury room and defy your ability to nullify if you choose to do so? If he said the moon was made of green cheese, would that statement affect in any way the chemical composition of the moon?
