Remember, remember, the fifth of December (1933) and that even a bad constitutional amendment could be repealed.
So might it happen with all bad laws.
According to This Day In History:
…..Congress passed the Volstead Act on October 28, 1919, over President Woodrow Wilson‘s veto. The Volstead Act provided for the enforcement of Prohibition, including the creation of a special Prohibition unit of the Treasury Department. In its first six months, the unit destroyed thousands of illicit stills run by bootleggers. However, federal agents and police did little more than slow the flow of booze, and organized crime flourished in America. Large-scale bootleggers like Al Capone of Chicago built criminal empires out of illegal distribution efforts, and federal and state governments lost billions in tax revenue. In most urban areas, the individual consumption of alcohol was largely tolerated and drinkers gathered at “speakeasies,” the Prohibition-era term for saloons.
Prohibition, failing fully to enforce sobriety and costing billions, rapidly lost popular support in the early 1930s. In 1933, the 21st Amendment to the Constitution was passed and ratified, ending national Prohibition. After the repeal of the 18th Amendment, some states continued Prohibition by maintaining statewide temperance laws. Mississippi, the last dry state in the Union, ended Prohibition in 1966.
