In order to apprehend a criminal the first steps involve evidence collection. CSI technicians collect blood samples either by submitting a piece of clothing or by using a sterile cloth and a small amount of distilled water to remove some blood from the body as well as collect blood samples by scraping trace blood spatter from walls and floors into a sterile container using a scalpel. Blood samples are also collected from the body. These samples are then sent to be analyzed to determine if the samples are the same since any blood at the crime scene may belong to either the victim or assailant. The lab will perform DNA analysis on the sample as well as the victim to determine whether or not it can be used later to compare to blood taken from all suspects.…

The FBI had just been created and were young so they didn't really know what they were doing yet. J. Edgar Hoover moved up through the ranks pretty fast and became the Director of the FBI. When Hoover became Director he weeded out all the political hacks and laid down strict rules for agents. He made all agents have background checks, interviews, and physical tests. Hoover took over in 1924, the Bureau had about 650 employees, including 441 special agents. Within five years it had just 339 special agents and less than 600 total employees. Some things they came up with to find and catch criminals were Fingerprints. All prisoners were fingerprinted so they could be kept track of and they were all recorded. By the time they were done they had more than 800,000 individual records. Another thing they did was created a scientific crime lab. The lab provided scientific examinations and analysis for the Bureau and its partners around the country. In just a few years, thanks to the successful battle against gangsters, the Bureau became very popular. Congress then gave new powers which gave them the abilities to carry guns and make arrests. In July 1935 the organization was renamed to the Federal Bureau of…

The formation of the FBI goes back to a group of special agents created in 1908, by Attorney General Charles Bonaparte, under President Theodore Roosevelt. It sprung up during the Progressive Era, a time when people supported a crime intervention team and believed government intervention was necessary in this type of society. Congress was also very supportive toward the Attorney General's plan. They enacted a law preventing the Department of Justice from engaging in secret service operatives, giving all of the investigative power to Bonaparte and his team of special agents. On July 26, 1908, Bonaparte ordered his special agents to report to Chief examiner Stanley W. Finch. This force of agents was later named the Bureau of Investigations by…
