As dusk settled on the era of prohibition, the United States was in the midst of a crime wave that spread across the nation. Would be bootleggers turned their attention to other vice trades including holdups, bank robberies and kidnappings. The introduction of powerful getaway cars and high capacity Thompson submachine guns allowed criminals to outrun and outgun the law.
FDR's New Deal program created public works projects with the hope they would help move the nation out of the Great Depression that hit the economy in 1929. A part of this program would be to focus on stopping cross-state crimes that were the calling card of the modern gangster and bank robbers. Laws were created for this purpose and their enforcement would be left to a small, then unknown agency, that would eventually become the Federal Bureau of Investigations.
As the Federal Prison population swelled and the prisoner's names became more infamous, there was a clear need for a place to house the worst of the worst from across the nation. The opening of Alcatraz Federal Prison signified a major change in the way the U.S. Government handled mobsters and outlaws. The reign of gangsters bootlegging, running brothels, speakeasies, protection rackets, gambling wires and cold blooded gangland killings were coming to an end. Most of the criminals would not survive being hunted by the law, but many of those that did would find themselves in the state-of-the-art prison: Alcatraz.
