BTW, it is highly doubtful that each co-defendant would have the same defenses. Much like the January 6th prosecutions, one's individual actions and "intent" are paramount in assessing criminality.
Have not seen any of the video or read witness accounts or seen social media posts. The DOJ has. These prosecutions are carefully vetted before indictments are filed. The DOJ does not indict these cases without compelling evidence.
The defense strategy is to emphasize what the client did NOT do -- no threats, didn't touch anyone, didn't obstruct any patient's path, didn't go to patient's house or workplace, etc --- and then argue (legally) to judge, and (factually) to jury that there was zero criminal intent ... that is the law requires much more egregious conduct to meet the threshold for criminality.
