When I lived there from 1977 to 1994, violence was not unknown. We had an Asian gang shoot out in the local upscale mall. Racist threats and violence were not unknown as sadly I know from personal experience. The neighbors got into and launched some 45 ACP through their house and into the neighborhood. Avoided a mini neighborhood, everybody from the bar spills out into the street to slug it out by making an illegal U turn and fleeing.
