The Los Angeles Parker moved to in 1922 had a similar complexion, albeit on a larger scale. Of its 520,000 residents, only about 15,000 were black. Most African American residents lived east of Main Street. The oldest black neighborhoods were near downtown, south of the rail yards along Central Avenue. By the 1920s, another sizable African American community had formed in nearby Watts. Most were drawn to the area by construction jobs building two major lines of Henry Huntington’s Pacific Electric streetcar system—the north-south line from downtown L.A. to Long Beach and an east-west line from Venice to Santa Ana. When the lines were completed, they simply stayed, creating a mixed black-Latino area known as Mudtown.
As the 1920s progressed, the influx of African Americans to the Watts area accelerated. In 1926, Watts was incorporated into Los Angeles, in part to prevent the emergence of an independent, majority-black city. Three years later, the Supreme Court upheld the legality of racially restrictive housing covenants designed to keep West Slauson Avenue white. African Americans were slowly being confined to the south-central area. The upside of this concentration was political power. Unlike African Americans in the Jim Crow South, black Angelenos were never denied the right to vote. As a result, as soon as the early 1920s, black voters were seen as an important voting bloc. A handful of black Political bosses soon emerged. Unfortunately, this was not a wholly positive development. These figures weren’t just ward bosses; they were also crime lords. Instead of improving Central Avenue, many used their clout to create zones of protected vice. Said one police officer in the 1930s, “I know the payoff men, I know the go-betweens; but what can I do when it’s sanctioned by the city’s politicians?”
The situation satisfied no one. Law-abiding residents felt ignored by the police. In turn, the police came to associate Central Avenue—and African Americans in general—with crime and vice. When politics demanded a crackdown, Central Avenue was an easy target. The result was a strained relationship between African American residents and the police.
As a policeman, Parker didn’t have much firsthand experience in dealing with black people. Only about 2 percent of the force was African American, a percentage that roughly reflected that of the population as a whole. Although he’d worked in the Central Division as a young policeman, his recollections of his early days as a patrolman seem largely devoid of black people. (In contrast, his stint as a sergeant in Hollenbeck in the early 1930s clearly did affect his perception of Latinos.) Had Los Angeles remained a city with only a small African American population, this might not have mattered much. But it did not. For at the same moment that Bill Parker was shipping out to join the U.S. Army, Los Angeles was becoming a major destination for African Americans.
The primary draw was jobs. The need to arm America’s forces in the Pacific had transformed Los Angeles into a major industrial center. But L.A. also seemed to offer blacks an escape from the Jim Crow South, at least at first glance. African Americans responded to this new opportunity by migrating west by the thousands. In 1941, the year before Bill Parker left Los Angeles to join the U.S. Army, Los Angeles’s African American population numbered approximately 70,000 residents. By the time he returned, Los Angeles had become a city with the largest African American population west of St. Louis, with an African American population of more than 125,000.
