New Crimes: Mob Intimidation
Answer
Even if something is not deemed a riot, it could be deemed mob intimidation, which carries a penalty of up to a year in jail:
It is unlawful for a person, assembled with two or more other persons and acting with a common intent, to use force or threaten to use imminent force, to compel or induce, or attempt to compel or induce, another person to do or refrain from doing any act or to assume, abandon, or maintain a particular viewpoint against his or her will.
There is no definition of “force” or “threaten to use imminent force,” and we expect that law enforcement will interpret this very broadly.
