Since Cermak and Mrs. Gill were still alive, Zangara was arraigned on four counts of assault with intent to kill, with a murder charge pending should one or both of them die. He insisted on pleading guilty, saying, "I kill capitalists because they kill me, stomach like drunk man. No point living. Give me electric chair." Sentenced to four terms of 20 years each, he told the judge, "Don't be stingy, give me hundred." He rejected an appeal.
The whole picture changed for Zangara when Anton Cermak died on March 6, two days after FDR's inauguration. His death came about through a misdiagnosis of his injuries that his doctors tried to cover up by citing a pre-existing condition. This opened a legal door for Zangara to claim that his bullet had not caused Cermak's death, but he insisted on pleading guilty.
He was electrocuted on March 20 in what still stands as the swiftest legal execution in this century. It's a measure of his unknowable personality that he was able to be both stoic and cocky in the death chamber. To the minister intoning sonorous prayers he snapped, "Get to hell out of here, you sonofabitch," and strode toward the chair unassisted, shouting, "I go sit down all by myself." A reporter-witness compared it to a man hopping into a barber's chair. As they put the hood on him he called out, "Viva Italia! Goodbye to all poor peoples everywhere!" His last words, spoken to Sheriff Hardie at the controls, were "Pusha da button!"

Sorry to hijack the thread, but this was fascinating. The things I learn looking up other things.
