Firearms evidence examination and fingerprint comparison have had a long and interesting history. The role of fingerprints in human identification can actually be traced back several thousand years. The development of the science of fingerprint comparison and the scientific examination of firearms, however, began in the early 19th century. The goal of the preservation of physical evidence is to associate each piece of evidence with its responsible source, allowing forensic scientists to answer questions regarding the who, what, when, where, how, and why of a crime. ""Firearms and Fingerprints"" traces these early beginnings and the icons that laid the groundwork for the current science.
