This is only intended to apply in a situation where we have the definition of it being an unlawful assembly or a riot. When an individual comes to a legitimate peaceful gathering—regardless of any type of facial covering, mask, or disguise that the person would choose to wear to a peaceful legitimate gathering—those provisions would not apply in that instance. They would apply in instances where there is an unlawful assembly or a riot. That's the only situation in which it would apply. It's meant as a tool to ensure public safety when situations like that occur, not at any kind of legitimate peaceful gathering.
