By connecting Michael Brown’s tragic death to the broader pattern of segregation and ghetto formation in the United States, Rothstein emphasizes the connection between
de jure segregation and the criminalization and police abuse of minority youth—namely, both are ways of sustaining the racial caste system, or ensuring that African American people remain second-class citizens. Recognizing the legal danger in following Louisville’s precedent, St. Louis’s zoning laws were never explicitly racial, but any close analysis of them makes it clear that they were consistently motivated by racism and officials’ desire to isolate African American people. However, because they did so through euphemistic language and policies that did not explicitly mention race, they maintained plausible deniability. Zoning African American neighborhoods for industrial development and seedy, exploitative industries was a triply oppressive strategy: it ensured that conditions would deteriorate and grow more dangerous, it provided white people with a further incentive to avoid living in area, and it helped reinforce associations between blackness and criminality.
