History: Prohibition Of Alcoholic Beverages, Los Angeles, California, United States

Organized crime received a major boost from Prohibition. Mafia groups limited their activities to prostitution, gambling, and theft until 1920, when organized bootlegging emerged in response to Prohibition. A profitable, often violent, black market for alcohol flourished. Powerful criminal organizations corrupted some law enforcement agencies, leading to racketeering. Prohibition provided a financial basis for organized crime to flourish.
Rather than reducing crime, Prohibition transformed some cities into battlegrounds between opposing bootlegging gangs. In a study of more than thirty major U.S cities during the Prohibition years of 1920 and 1921, the number of crimes increased by 24 percent. Additionally, theft and burglaries increased by 9 percent, homicides by 12.7 percent, assaults and battery rose by 13 percent, drug addiction by 44.6 percent, and police department costs rose by 11.4 percent. This was largely the result of “black-market violence” and the diversion of law enforcement resources elsewhere. Despite the Prohibition movement's hope that outlawing alcohol would reduce crime, the reality was that the Volstead Act led to higher crime rates than were experienced prior to Prohibition and the establishment of a black market dominated by criminal organizations.
Furthermore, stronger liquor surged in popularity because its potency made it more profitable to smuggle. To prevent bootleggers from using industrial ethyl alcohol to produce illegal beverages, the federal government ordered the poisoning of industrial alcohols. In response, bootleggers hired chemists who successfully renatured the alcohol to make it drinkable. As a response, the Treasury Department required manufacturers to add more deadly poisons, including the particularly deadly methyl alcohol. New York City medical examiners prominently opposed these policies because of the danger to human life. As many as 10,000 people died from drinking denatured alcohol before Prohibition ended. New York City medical examiner Charles Norris believed the government took responsibility for murder when they knew the poison was not deterring people and they continued to poison industrial alcohol (which would be used in drinking alcohol) anyway. Norris remarked: "The government knows it is not stopping drinking by putting poison in alcohol..."Yet it continues its poisoning processes, heedless of the fact that people determined to drink are daily absorbing that poison. Knowing this to be true, the United States government must be charged with the moral responsibility for the deaths that poisoned liquor causes, although it cannot be held legally responsible."
Another lethal substance that was often substituted for alcohol was "canned heat," also commonly known as Sterno. Forcing the substance through a makeshift filter, such as a handkerchief, created a rough liquor substitute; however, the result was poisonous, though not often lethal. Many of those who were poisoned as a result united to sue the government for reparations after the end of Prohibition.
