If a student or anyone ever came into a classroom and it was disruptive, it's always the faculty person's right to ask that person to leave and if they wouldn't leave to call the police and ask the police to remove the person.
I think it's less about coming up with a list of what is or is not allowed, and it's more about making sure people understand the classroom is supposed to be a place where learning can go on, and if it's disruptive, people have the authority to eliminate disruption.
