Testimony in Favor of the Death Penalty

Justice Lewis Powell
United States Supreme Court Justice
excerpts from McCleskey v. Kemp, 481 U.S. 279 (1987)
(footnotes and citations omitted)

(Mr. McCleskey, a black man, was convicted and sentenced to death in 1978 for killing a white police officer while robbing a store. Mr. McCleskey appealed his conviction and death sentence, claiming racial discrimination in the application of Georgia's death penalty. He presented statistical analysis showing a pattern of sentencing disparities based primarily on the race of the victim. The analysis indicated that black defendants who killed white victims had the greatest likelihood of receiving the death penalty. Writing the majority opinion for the Supreme Court, Justice Powell held that statistical studies on race by themselves were an insufficient basis for overturning the death penalty.)

“[T]he claim that [t]his sentence rests on the irrelevant factor of race easily could be extended to apply to claims based on unexplained discrepancies that correlate to membership in other minority groups, and even to gender. Similarly, since [this] claim relates to the race of his victim, other claims could apply with equally logical force to statistical disparities that correlate with the race or sex of other actors in the criminal justice system, such as defense attorneys or judges. Also, there is no logical reason that such a claim need be limited to racial or sexual bias. If arbitrary and capricious punishment is the touchstone under the Eighth Amendment, such a claim could -- at least in theory -- be based upon any arbitrary variable, such as the defendant's facial characteristics, or the physical attractiveness of the defendant or the victim, that some statistical study indicates may be influential in jury decision making. As these examples illustrate, there is no limiting principle to the type of challenge brought by McCleskey. The Constitution does not require that a State eliminate any demonstrable disparity that correlates with a potentially irrelevant factor in order to operate a criminal justice system that includes capital punishment. As we have stated specifically in the context of capital punishment, the Constitution does not 'plac[e] totally unrealistic conditions on its use.' (Gregg v. Georgia)”
