Guy B. Johnson, quoted in Isabel Wilkerson’s Caste, wrote:
“This fact [total control over slaves] is of great significance for the understanding of racial conflict for it means that white people during the long period of slavery became accustomed to the idea of ‘regulating’ Negro insolence and insubordination by force with the consent and approval of the law.”
And thus we see some police officers maintaining this control via many methods: overpolicing, surveillance of non-criminal activity, excessive force in arrests, home invasions with or without a warrant, harassing traffic stops, and outright murder.
