Just wonder where your rights as a property owner would end? If my business, home, car or other property were being destroyed I might be tempted to do some counter protesting with my Remington 870 loaded with 3 inch 00.
In CA you have no property rights. :P
During the LA Riots (post Rodney King), the Korean shopkeepers kept rioters away with guns. The shopkeepers were on their shop roofs. Nobody messed with them, either.
