In 1908, United States Attorney General Charles J. Bonaparte established the Department of Justice Bureau of Investigation (BOI). Its goal was to “investigate violations of laws in the United States and gather evidence in cases involving the United States.” The office's power would be limited by the fact that most government departments already have investigative measures in place. The Federal Bureau of Investigation (FBI), as it was later called, took a turn when Attorney General Harlan Stone appointed John Edgar Hoover as acting director of the FBI on May 10, 1924 (Current Biography 254). In turn, J. Edgar Hoover, incorporating new scientific advances, reinventing the "agent," and defeating gangsters, expanded everything. It all started with the agent. The previous director, William Burns, often employed political or unqualified personnel as agents. Hoover, being a progressive and a reformer, wanted to transform the BOI into a professional and respected department. He required special agents to undergo multiple interviews and background checks, as well as physical tests to ensure all men were qualified for the job (Current Biography 255). Furthermore, he also reinstated legal training by establishing the FBI National Police Academy, in 1935, in Quantico, Virginia, to not only train officers, but also police officers from across the nation (Kelly 32). This academy trained officers on how to conduct investigations. Officers then took this information and trained personnel in their region (Current Biography 255). This would ensure that techniques learned by the nation's top investigative department were also shared with officers and facilities across the country. However, this was only half of its original task. His next task was to make the FBI a “scientific and professional law enforcement agency” (Rosenfeld 405). This would involve exploiting the latest scientific technologies available. He began by establishing a campaign whose purpose was to collect the fingerprints of all Americans to help protect society and solve crimes (Kylig 179). This may be his most esteemed achievement since fingerprinting is one of the most widely used processes in the justice system. Along with a fingerprint registry, he also established a crime registry that would collect information from agencies nationwide and publish crime statistics. In the years to come, he would establish an FBI crime laboratory. This made it easier to conduct investigations and examine evidence more thoroughly. This laboratory was accessible to all law enforcement agencies nationwide respectively. Among all these advancements, it also established the “Ten Most Wanted” list. This helped the FBI track criminals who posed the greatest threat to society (Kylig 180). This ultimately helped Hoover achieve his goal of creating a professional, scientific police agency (Current Biography 254; Rosenfeld
