That's called chaos, not order. Only "designated police force" is enitled for action by design, not the unauthorized civilians, who think "police is not doing enough, so let's take the gun".
If an anti social element comes to your neighborhood and provokes you, you don't take the gun and go after them. You report the matter to police for them to handle. No city and no country has enough security forces, so there can be delay in action or in some cases, inaction, that doesn't call for you to take the gun and go out. In all likelyhood, that is what is intended by those that are provoking.
