Americans of all races, ethnicities, ages, classes, and genders have been subjected to police brutality. In the late 19th and early 20th centuries, for example, poor and working-class whites expressed frustration over discriminatory policing in northern cities. At about the same time, Jewish and other immigrants from southern and eastern Europe also complained of police brutality against their communities. In the 1920s many urban police departments, especially in large cities such as New York and Chicago, used extralegal tactics against members of Italian-immigrant communities in efforts to crack down on organized crime. In 1943 officers of the Los Angeles Police Department were complicit in attacks on Mexican Americans by U.S. servicemen during the so-called Zoot Suit Riots, reflecting the department's history of hostility toward Hispanics (Latinos). Regular harassment of homosexuals and transgender persons by police in New York City culminated in 1969 in the Stonewall riots, which were triggered by a police raid on a gay bar; the protests marked the beginning of a new era of militancy in the international gay rights movement. And in the aftermath of the 2001 September 11 attacks, Muslim Americans began to voice complaints about police brutality, including harassment and racial profiling. Many local law-enforcement agencies launched covert operations of questionable legality designed to surveil and infiltrate mosques and other Muslim American organizations in an effort to uncover presumed terrorists, a practice that went unchecked for at least a decade.Notwithstanding the variety among groups that have been subjected to police brutality in the United States, the great majority of victims have been African American. In the estimation of most experts, a key factor explaining the predominance of African Americans among victims of police brutality is antiblack racism among members of mostly white police departments. Similar prejudices are thought to have played a role in police brutality committed against other historically oppressed or marginalized groups.Whereas racism is thought to be a major cause of police brutality directed at African Americans and other ethnic groups, it is far from the only one. Other factors concern the unique institutional culture of urban police departments, which stresses group solidarity, loyalty, and a "show of force" approach to any perceived challenge to an officer's authority. For rookie officers, acceptance, success, and promotion within the department depend upon adopting the attitudes, values, and practices of the group, which historically have been infused with antiblack racism.Because African Americans have been the primary-though certainly not the only-target of police brutality in the United States, the remainder of this article will deal mainly with their experiences, both historically and in the present day.THE GREAT MIGRATIONInteractions between African Americans and urban police departments were initially shaped by the Great Migration (1916-70) of African Americans from the rural South into urban areas of the North and West, especially following World War II. Most white communities, including white police departments, were unaccustomed to the presence of African Americans and reacted to their increasing numbers with fear and hostility, attitudes that were exacerbated by deeply ingrained racist stereotypes. Reflecting the beliefs of many whites, northern police departments acted upon the presumption that African Americans, and especially African American men, possessed an inherent tendency toward criminal behaviour, one that required constant surveillance of African Americans and restrictions on their movements (segregation) in the interests of white safety. Accordingly, by the mid-1950s many urban police departments had implicitly re-conceived their missions as essentially that of policing African Americans-i.e., protecting whites against blacks.Get full book...
