Forensic science is generally defined to be the practical application of enormous field of science to gain solution for legal system-related queries that may include the criminal or civil suit and actions. This scope has been extensively widened into a broad range of sub-topics that apply the natural scientific techniques and procedures to disclose pertinent legal and criminal evidences. In fact, this field has begun evolving since 212BC and the development of using fingerprints to detect unique human identity has been introduced even during the 7th century.
Due to long phrasing terms, people have typically shortened them to be “forensics”. The usage of this term to replace the original label has become a universally-accepted misnomer as the term is equivalently a synonym for the phrases “pertaining to courts” or “legitimate”. Due to its close association with the criminal scientific study, most of the dictionaries are now equating the original name with the new term.
Speaking of the history of forensic science, it was announced far as back as during the Roman Empire. There was a criminal charge wanting to confront a group of public peers to voice their pleading where both the accused and the accuser each gave a speech of defending story. Any of them who came up with the best argumentation and speech delivery skills would determine the verdict of the case. Of course, the man with the greatest debate and forensic skills steal the victory, operating much like what the attorney and lawyers do at this day.
In direct relation to the field of forensics study and research is the Crime Scene Investigation (CSI), although both disclose distinctive differences. The main task of a Crime Scene Investigator is to accumulate, discover, document and preserve any physical evidence found at the criminal scene, planted with the ultimate purpose of displaying a list of identification evidence at the court to apprehend the perpetrator. CSI is a field combined with broad science knowledge as well as techniques of various disciplines encompassing logic, law and mathematics.
