Examining Black women's experiences with policing, this article argues that police terror is not predicated upon gender; rather, it enacts gender by undoing gender. Thus, it requires a new arithmetic of time and space in order to read beyond normative, hypermasculine narratives of police violence. While the dominant discourse of race and policing asserts that police terror disproportionately affects Black men, the frequency of Black women's experiences with police terror attunes to a lingering yet deadly impact beyond the linear, Cartesian dimensions of body counting, a frequency the article terms sequelae. Policing stretches and bends time and space as part of its (un)gendering practice. Through a brief survey of cases in Brazil and the United States, this article considers sequelae as a new arithmetic for calculating the multiple frequencies of police terror against Black women. Specifically, the article examines the case of Luana Barbosa dos Reis, a Black lesbian mother who was beaten to death by police officers in São Paulo in 2016. The article argues that her beating was an act of (un)gendering—a desire to both discipline her as a Black female/mother and erase her potential humanity by denying her desired gender identification (female). In this sense, her death was an act of anti‐Black terror “in the wake.” Through a close reading of the police ledger, the police report, and the physical violence she endured, the article argues that her story teaches us the need for a new way of counting the frequency of police terror in relationship to time, space, and the Black female/mother body.
