Haven't checked yet but just now saw a short news report that at a uni in Washington uni authorities had asked police to halt a tent demonstration but police had said they won't unless a law had been broken. That should always be the case.
And there should be no doubt in anyone's mind that extreme right-wingers and extreme left- anarchists would be attempting to use peaceful demos to push their own different agendas.
That fact media should keep front and center also, with at least one sentence in virtually every demonstration story.
