Hugo Black,
Smith v. Texas (311 U.S. 128)…
“ What the Fourteenth Amendment prohibits is racial discrimination in the selection of grand juries. Where jury commissioners limit those from whom grand juries are selected to their own personal acquaintance, discrimination can arise from commissioners who know no negroes as well as from commissioners who know but eliminate them. If there has been discrimination, whether accomplished ingeniously or ingenuously, the conviction cannot stand. ”
