When Mother Henry points out that white people never referred to her respectfully (as “Mrs. Henry”) until her grandson was murdered, she is underscoring the racist cultural context in which Lyle’s trial is taking place. In the same vein, when the State speaks on behalf of every
white person in town, it shows that the State thinks of himself as a representative of whiteness—and thus highlights that the State’s defense of Lyle is part and parcel of defending white supremacy. Finally, the audience knows that Mother Henry is lying when she says she never saw a gun. Her lie under oath implies that she’s sure Richard—not Lyle—is on trial here, and that the white jury would become irremediably prejudiced against Richard if they knew he was a gun owner. This double standard shows that, in this white-supremacist context, Black people are not afforded the same right to violent self-defense that white people are.
