Cop shows such as Dexter and the CSI franchise have spiked the public's interest in forensic science. But, what does a forensic scientist or investigator actually do for a living? Is it as exciting as depicted on these and other TV shows? And, does the term “forensics”…
Forensic science is merely using science and scientific techniques to examine evidence found at crime scenes. Evidence varies from fingerprints and bodily fluids to firearms and bone fragments. It can also include clothing and fibers, tire and shoe prints, and even traces of explosive or flammable substances in bombing or arson investigations. In other words, forensic scientists work with the police and federal agents to reconstruct crime scenes and to bring criminals to justice. They may also be employed by defendants to provide testimony in civil and criminal cases.
There are specialties in forensic science as there are in medicine. Some forensic experts focus on the physical evidence, collecting and analyzing samples, taking fingerprints, and reconstructing the crime scene. Others focus on forensic psychology, helping victims deal with their trauma or determining if someone is competent to stand trial or treating sex offenders. Still others specialize in computer forensics. Instead of blood or DNA samples, they collect and analyze information in cases involving industrial espionage, the disclosure of personal information, or data lost in a systems crash. Even handwriting analysis is a form of forensic science when it is employed, for example, to verify the signature on a document.
Getting into forensic science means majoring in a scientific discipline like chemistry or physics. It also means taking classes in the law and even communication. Practical experience in a laboratory setting is also helpful. Pay averages about $41,000 a year, but varies with specialty and location.
