End Of Prohibition
The thirties was the beginning of the end for prohibition on
a national scale. The 21st amendment was the one that ended it in 1933. The reason
for prohibitions demise was that it started losing popularity with people and
costing the government millions of dollars trying to keep it off the street and
protecting people like Al Capone and other gangsters. So as you can see the
gangsters did have an impact on prohibition.
