As the title suggests, tonight's case from your FBI concerns a kidnapping. Styles change in crime, just as they do in automobiles and clothes. There used to be an estimated 3000 kidnappings a year in the 1930s, but by the 1950s there were comparatively few. That happy situation has not become about because criminals became tired of collecting ransom... It was the direct result of two things. The first was the kidnapping law passed in the 1930s, and the second is a man ... J Edgar Hoover.
