The Science Behind Crime Scene Investigation
Forensic science has developed into a scientific discipline that is used in various applications in various fields involving legal implications and to help solve cases with criminal or civil suits and related disputes.
The scope of the forensic science has evolved over the years to include several branches that use natural scientific techniques and methods to examine and determine several legal and criminal evidences. It is said that the forensic science as such originate and began to be developed around 212 BC and even as early as 7th century, humans had developed the system of finger printing as unique mark of identification.
Over the years people have begun referring to the field as forensics thus replacing the long phrasing terms. This has now become universally acceptable term and is also used as a misnomer to mean and refer to as a synonym for “legal things and legitimate” phrases.
With the universal usage and acceptance of the term forensics referring to use of scientific study in criminal field, even the dictionaries and academics have begun to accept and use the new term along with the original name as an equivalent term.
Forensic science seemed have been developed and used extensively even during the Roman Empire. History records show that an assembly of public peers would be convened to evidence the proceedings of a criminal case where both the accused and the accuser would be given chance to argue their case.
The verbose argumentation and demonstration of skills in arguments coupled with forensic skills to present evidence and argue the case based on logic and evidence seemed to make the best presenter win the case very similar to the modern day courts and lawyers arguing the cases in courts today.
In a way the science of a Crime Scene Investigation as well as forensics study seem to be apparently overlapping and related through very different and distinctive in their final purpose. The role of a Crime Scene Investigator is more to do with discovery, collection, documenting and preserving of physical evidence at site that is later used to present along with evidence as identification in the court to be able to apprehend the perpetrator.
