This is designed to apply to those who are participating in a riot or unlawful assembly. Anyone who is participating in a riot or unlawful assembly who is disguising their identity would face the sanctions of this bill. I would certainly hope we would not see a situation where that would come into play. Anyone who is involved in participating in a riot or unlawful assembly would fall under the provisions of this bill.
