As the blood of criminal violence flowed through the streets in early 1920s America, the FBI was rendered helpless by unholy alliances with crooked politicians & shady dealings. After being named dir. of the FBI, Hoover quickly whipped the bureau into crime-fighting shape through mass firings & screening of new recruits. Hoover"s revitalization of the FBI resulted in the forming of a small efficient force. Once Congress removed limitations on making arrests & carrying firearms, Hoover & 600 "G-Men" took to the streets, matching guns & wits with America"s most notorious gangsters. The G-Men nailed criminals & kingpins such as John Dillinger, "Baby Face" Nelson, "Pretty Boy" Floyd, & "Machine Gun" Kelly. Gripping accounts of actual incidents!
