Aldridge v. United States
In Aldridge v. United States, 283 U.S. 308, 51 S. Ct. 470, 75 L. Ed. 1054, 73 A.L.R. 1203 (1931), the defendant was an African-American male and the victim was a Caucasian police officer.
Defense counsel requested the trial court to question prospective jurors whether they might be prejudiced against the defendant because of his race.
The Supreme Court held it was reversible error for the court not to have posed such a question, observing that "'the Court failed to ask any question which could be deemed to cover the subject.'" Id. at 422-23.
