How The Forensic Scientist Role Has Dramatically Changed Over The Decades

Owing to the evolution of science, forensic scientist roles have considerably changed, and became more multi-faceted. In the early days of forensics, around a century ago, scientists were mainly concerned with the analysis of crime scenes. This was a development from several unrelated cases where crime scene evidence had led to a conviction, including one celebrated case where a bloody fingerprint could be matched to the prints of the murderer. Most forensics today still deals with crime scene evidence, but there have been other significant developments using new technology.

Forensic scientists'daily bread is the analysis of crime scene evidence, and to draw far reaching conclusions from it. Fingerprinting is only one example of how information left inadvertently is recorded and used. It remains one of the most useful techniques available to the forensic expert, because it offers a unique and totally definitive answer to the question of who used a certain object, or touched a certain door or wall. The prints left in soft earth by shoes can obviously be analyzed, but it is far harder to draw definite conclusions.

Another dimension added to forensic science is the fact that vehicles are so often used in crimes. Tire tracks can be analyzed to determine the make and model of a vehicle which has been driven from a road into a secluded soft earth area, although it is always possible for criminals to change the tires later. The depth of the markings, and their angle, can also be used to provide useful clues. Sometimes, the scientist is given more to work with, such as when rare oil from a motorcycle was deposited near a murder scene, allowing the murder to be identified.

Recent developments in forensic science have brought forward a new class of scientist. Digital media have become their work tool. When computers and other electronic devices are seized from those suspected of being criminals, they are routinely analyzed to see if there is any significant data in their memory banks. When electronic files are deleted, the user often assumes that they are gone for ever. That is rarely the case, as they remain in the memory until they are overwritten be fresh data. A qualified scientist with the right software can easily access them.

Though many specialists only work in a limited range, you might realize that the role of a forensic scientist nowadays encompasses a wide range of techniques. If you have the desire to work in forensic science, it will be a good idea to know in advance which discipline you would want to specialize in, although a good grounding in all aspects of the science is a great asset. If you can get a place at a police training center, and then work with an experienced scientist, you can yourself become a qualified forensic scientist.
