Gambling in the 1930s and 1940s was instrumental in Jeffersonville's recovery from the Great Depression and the Flood of 1937. Casinos, betting parlors, night clubs, and even a dog track were present, giving the town the nickname "Little Las Vegas". After Clarence Amster, a New Albany businessman was gunned down on July 2, 1937, public sentiment turned against gambling. On January 2, 1948, Indiana State Police raided every casino in the city before the operators could warn each other, and the judge who had devoted the past nine years to eliminating gambling from Jeffersonville, James L. Bottorff, ensured that the equipment was confiscated and the money at the casinos given to charity. This may have played a factor in keeping Jeffersonville residents from voting to approve riverboat gambling in the 1990s. In 2006, riverboat gambling was approved, but for the return of gambling to occur the Indiana State legislature would either have to approve an additional riverboat, or one of the existing riverboats in Indiana would have to relocate to Jeffersonville; presumably, it would be one of the three currently serving the Cincinnati market.
