How the FBI dealt with "The Roaring Twenties"

     The Federal Bureau of Investigation struggled in the 1920's to find sufficient evidence to convict the gangsters of the '20's.  The FBI had another problem other then the mobsters, the Ku Klux Klan.  The FBI used the Mann Act to bring the KKK to justice.
      On August 21, 1920 the Chicago division of the FBI was created to help to contain the mobsters that were stationed in Chicago.  Mobsters such as John Dillenger and Al Capone resided in Chicago.
     On May 10, 1924 J. Edgar Hoover was appointed as the head of the FBI.  At this time the FBI consisted of 650 employees with 441 special agents.  Hoover enstated the rule that new agents had to between 25 and 35 years of age.  He also created 30 field offices and had reagular inspections of all operations at all the different cities.  He had all the divisions of the FBI in the different cities start a fingerprint collection of the criminals they brought in. 
      The Chicago division of the FBI had a large task to try and eliminate all the gangsters that resided there in the 1920's.  On Feb, 14, 1929 the ST. Valentine's Day Massacre occured in Chicago and the Chicago FBI did a ballistics test which led to the creation of the FBI lab which has been used to further assist the FBI agents in catching criminals.  On March 27, 1929 the Special Agents in Florida arrested Al Capone for failing to appear in court in Chicago.
