The case is in a different jurisdiction in another state. How is it anyone's business what he says in a private capacity about a case in someone else's bailiwick?
Doesn’t matter it’s a different jurisdiction. As a defense atty I’d be all over him on EVERY case especially anything in which he is involved in an altercation. And it would be relevant. It would go to his state of mind and motivation. It would color EVERY single case he handled involving minorities. Pretty much every judge on the planet would let it in. And if they don’t suspend him, it colors the whole department.
Suspend him at a minimum.
