Turf wars have been common in the older Chinatowns. Gang rivalry among Chinatown gangs has sometimes have a high profile. As Chinatowns tend to be tourist attractions, tourists in Chinatowns have sometimes been victims of these gang warfare crimes. In 1977, a shoot-out occurred in a San Francisco Chinatown restaurant (where the rival gang were normally based), in which two tourists and three waiters were murdered by stray gunfire in a botched assassination attempt on a Wah Ching gang member. Eleven other people were injured. This incident is notoriously known as the Golden Dragon massacre and it mobilized the San Francisco Police Department to create an Asian crime unit. The five suspects involved in the attack were sentenced and convicted. On June 30, 1995 involved two factions of the Jackson Street Boys. One faction opened fire on the other on a busy Chinatown street, Stockton Street, during the daytime. Seven innocent bystanders were struck, including a pregnant woman. Three males, ages 18, 16, and 14, were arrested in connection with the shooting. Jackson Boys were also the primary trafficker of illegal fireworks back when fireworks were blatantly sold on the streets of Chinatown. In June 1998, shots were fired at Chinese Playground, wounding six teenagers, three of them critically. A 16-year-old boy was arrested for the shooting, which was believed to be gang-related.
