I think Sam's argument is that the order was not "lawful". They'll certainly get them on interfering with "orderly conduct", since once you refuse to follow an order, lawful or not, your actions are generally going to be considered by the court to be disorderly.
I've got mixed feelings on this latest display. It does sound to me like Sam was over the top and was most likely not in that much pain. However, I wasn't there so I can't say one way or the other. In my opinion, everyone who was recording in the court room with the intention of distributing the footage to the public is a member of the press. Any order to prevent them from recording in a "public" space, therefore, should be considered unconstitutional.
