Prohibition
In 1919，a new law in the US known as Prohibition made it illegal to buy and sell alcohol．But Prohibition didn't stop people drinking； it just drove the sale of strong alcoholic drink underground．Bootleggers（走私贩） waited off the coast of New York after dark and brought illegal alcohol into the city．
