In January of 1920, the eighteenth amendment was introduced, which banned the manufacturing, transportation, importation, and sale of alcoholic beverages in the United States. This amendment became known as Prohibition, and it was much more unsuccessful than was planned by the government. Instead of eliminating liquor from the streets, Prohibition promoted the illegal transportation and production of liquor by raising prices of alcohol. There was a high demand for alcohol in the black market, therefore many kingpin mobsters began to produce liquor for sale. The high demand but low supply of alcohol meant that a huge profit could be made from this sale of illegal product. Therefore, many gangsters began to arise in society to take advantage of the opportunity. This included the well-known Al Capone. The distribution of liquor was much more complex than other methods of crime. First, the illegal alcohol had to be produced in a very hidden location. If this location became disclosed to the police, the entire operation would be immediately shut down. Next, the alcohol had to be bought or taken to a gangster or mob for distribution. Finally, the consumer had to make the purchase of the liquor. This step was obviously very informal. It was most commonly done on street corners or in hidden alleys that would not be noticed by police.
