Rational decent people have concluded that in Democratic urban areas, there has been a collapse of the criminal justice system. Emasculated police do not investigate crimes or arrest felons. DAs do not prosecute and judges do not imprison. Good people who by neccessity must visit, ork of worse live in such areas know that they themselves must protect themselves and others by any means necessary. This Israeli showed how its done.
Israel radically restricts ownership of firearms and ammunition. Even such restrictive laws result in civilian heroes.
