The Federal Bureau of Investigation (FBI) is a governmental division which belongs to the United States Department of Justice (2005). This organization plays an important role in federal criminal investigation and capturing internal intelligence (Pistole and Police). It was established in 1908 as the Bureau of Investigation, and reorganized in 1924. In 1935, its name was changed to FBI (Pistole and Police). From that time, the FBI totally investigates over 180 kinds of federal crimes, which contains hijacking, kidnapping, treason, espionage and some attacks of terrorism (Cornelison, 2004).
There is an important person occurred in the history of FBI’s development. J. Edgar Hoover, was an FBI Director who worked for this organization from 1924-1972. He witnessed the growth and change of this organization. In that period, he mainly focused on studying how to create the Scientific Crime Detection Laboratory in order to help government to professionalize the working structure and detective methodology. Moreover, he used his working experience and ability to work out many complicated cases. Therefore, he made a great contribution to the FBI’s further investigation. Throughout the history of the FBI, Hoover is the only one person that has a 48-year tenure (Pistole and Police).
In addition, the FBI has many branches and a huge scale. Their international offices named “legal attaches” exist in their national embassies in more than 50 countries around the world.
