In telling the Sweets’ story, the book claims that justice cannot exist until all people have equal civil rights in theory and in practice. Schuknecht’s divided loyalties show why. On the one hand, as a police officer, he’s supposed to protect all citizens; on the other hand, he empathizes with the white neighborhood residents, including his own relatives. And by late summer of 1925, it’s become clear that most of the predominantly-white Detroit police force, like Schuknecht, prefers to protect the interests of other white people, pointing to the systemic prejudice that Black Detroiters face.
