exam and in every promotional exam thereafter. On his promotion to lieutenant, he rejoined Chief Parker as Parker's executive officer. He was promoted to captain, responsible for intelligence. By the time of the Watts riots in 1965 he was an inspector (overseeing the investigations of, among other crimes, the Manson Family murders and the Hillside Strangler case). By the time of the 1975 special investigation into the assassination of Robert F. Kennedy he was Assistant Chief of the Los Angeles Police Department. On March 28, 1978, Gates became the 49th Chief of the Los Angeles Police Department. SWAT Gates established the specialized unit to become known as SWAT (originally, "Special Weapons Attack Team" but changed to "...And Tactics" for optics) in order to deal with hostage rescue and extreme situations involving armed and dangerous suspects. Ordinary street officers, with light armament, limited weapons training and little instruction on group fighting techniques, had shown to be ineffective in dealing with snipers, bank robberies carried out by heavily armed persons, and other high-intensity situations. In 1965, Officer John Nelson came up with the idea to form a specially trained and equipped unit to respond to and manage critical situations while minimizing police casualties. As an inspector, Gates approved this idea. He formed a small select group of volunteer officers. His first team was born LAPD SWAT, D-Platoon of the Metro Division. This unit initially comprised fifteen teams of four men each, for a total staff of sixty. These officers were given special status and benefits, but in return they had to attend monthly trainings and serve as security for police facilities during episodes of civil unrest. SWAT was copied almost immediately by many US police departments and is now used by law enforcement agencies throughout the world. In Gates' autobiography, Chief: My Life in the LAPD (Bantam Books, 1992), he explained that he developed neither SWAT tactics nor its distinctive equipment. He wrote that he supported the concept, tried to empower his people to develop the concept, and lent them moral support. PDID Gates made substantial use of the LAPD's Public Disorder Intelligence Division (PDID) squad, even developing an international spying operation. The lawsuit CAPA v. Gates, with the Coalition Against Police Abuse (CAPA) as one of two dozen or so plaintiffs, later sued the LAPD on First Amendment grounds that exposed the unlawful harassment, surveillance, and infiltration of the progressive movement
