Missouri
More than three-quarters of Missouri voted to repeal Prohibition on August 19, 1933. Ten days later, on August 29th, a convention took place ratifying that decision. Missouri's experience with Prohibition was characterized by overzealous enforcement by officials who were sometimes criminals themselves.
In April of 1925, a story ran about how the federal government, in response to reports of bootlegging on some islands on the Missouri River, decided to bomb the islands with mustard gas.
Also in 1925, one patrolman and another former policeman tried to steal liquor from a bootleggers' cave, which evidently didn't sit well with the bootleggers. The two men were later found dead, with “blows on their head and their throats. . .cut.”
