Arkansas can force a prisoner on death row to take antipsychotic medication to make him sane enough to execute

The New York Times reports:
"Singleton presents the court with a choice between involuntary medication followed by an execution and no medication followed by psychosis and imprisonment," Judge Roger L. Wollman wrote for the majority in ruling by the United States Court of Appeals for the Eighth Circuit.

Judge Wollman said the first choice was the better one, at least when the drugs were generally beneficial to the prisoner.
