Once the gallows went behind prison walls, reformers asked how an execution should be done and answered with science. New York chose electricity in 1888 amid the Edison-Westinghouse commercial war, and the first electrocution took two currents. Nevada chose gas in 1924. In 1946 Louisiana's chair failed to kill seventeen-year-old Willie Francis and the Supreme Court allowed a second try: a method declared humane, a failure, a new method.
Whether the Louisiana crew was drunk is an allegation by witnesses never tested in court. Whether Francis was guilty and whether Jesse Tafero was innocent are debated, and no court revisited Francis's verdict. Whether the Francis precedent governs a case where drugs were actually given is open.
