Forensics is the application of a wide variety of scientific methods and techniques in the investigation of a crime and establishing evidence in a court of law. The term “forensic” derives from Latin adjective forensis, meaning “of or before the forum” as in ancient Rome persons accused of a criminal charge were required to present the case before a group of public individuals in the forum. Today, the term “forensic” are effectively used as synonyms for “legal” or “related to courts”.
