Police power was built on women's bodies.Men, especially Black men, often stand in as the ultimate symbol of the mass incarceration crisis in the United States. Women are treated as marginal, if not overlooked altogether, in histories of the criminal legal system. In The Streets Belong to Usa searing history of women and police in the modern United StatesAnne Gray Fischer narrates how sexual policing fueled a dramatic expansion of police power. The enormous discretionary power that police officers wield to surveil, target, and arrest anyone they deem suspicious was tested, legitimized, and legalized through the policing of women's sexuality and their right to move freely through city streets.Throughout the twentieth century, police departments achieved a stunning consolidation of urban authority through the strategic discretionary enforcement of morals laws, including disorderly conduct, vagrancy, and other prostitution-related misdemeanors. Between Prohibition in the 1920s and the rise of "e;broken windows"e; policing in the 1980s, police targeted white and Black women in distinct but interconnected ways. These tactics reveal the centrality of racist and sexist myths to the justification and deployment of state power. Sexual policing did not just enhance police power. It also transformed cities from segregated sites of "e;urban vice"e; into the gentrified sites of Black displacement and banishment we live in today. By illuminating both the racial dimension of sexual liberalism and the gender dimension of policing in Black neighborhoods, The Streets Belong to Us illustrates the decisive role that race, gender, and sexuality played in the construction of urban police regimes.
