Forensic science (often known as forensics) is the application of a broad spectrum of sciences and technologies to investigate and establish facts of interest in relation to criminal or civil law. The word forensic comes from the Latin forensis, meaning "of or before the forum." In Roman times, a criminal charge meant presenting the case before a group of public individuals in the forum. Both the person accused of the crime and the accuser would give speeches based on their sides of the story. The individual with the best argument and delivery would determine the outcome of the case. This origin is the source of the two modern usages of the word forensic as a form of legal evidence and as a category of public presentation.
