I think I would have met the crowd with a shotgun.
The legal trickery used in this incident is astronomical. The cops were out of jurisdiction, so had no authority to act against the thugs, but could immediately act against a "threat" that produced a weapon, and that was the plan, to provoke the homeowner or family into a "brandishing" crime or other tort basis.
Legal trick: the out of jurisdiction cops cannot enforce the homeowners "trespassers get off my property" order, or any violation of required demonstration permits and demonstrator requirements (like: must keep walking), only local cops can.
with out a doubt........”911 my family is being attacked....I will be opening fire soon”
