In this chapter, data from the timeline referenced earlier will be used to illustrate the history of forensic science highlighting three important examples: fingerprints, crime laboratories and blood analysis. Most forensic science laboratories are associated with law enforcement agencies; for example, Detroit Police Department Crime Lab, Indiana State Police Forensic Lab, FBI Lab. The websites of any of the federal agencies listed in the section on the organization of Federal forensic science labs will provide information about how one joins that organization as a forensic scientist. The FBI lab is one of the best-known and most prestigious forensic science laboratories in the world. It has all of the forensic science services needed in the state including toxicology and behavioral forensic sciences. In a country the size of the United States but with 10% of the population, where most people live on the coast, one would expect a different type of forensic science system.
