Crime scene investigations involves employing forensic science tools, procedures, and processes to investigate a crime scene and the collection of forensic evidence.
Forensic science, more commonly known as forensics, is the application of sciences to answer questions of interest to a legal system. Forensics may be used to answer questions in relation to a crime or a civil action. Forensics encompasses the accepted scholarly or scientific methodology and norms under which the facts regarding an event, or an artifact, or some other physical item (such as a corpse) is ascertained as being the case. The concept, therefore, is related to the notion of authentication, whereby an interest outside of a legal form exists in determining whether an object is what it purports to be, or is alleged as being.
The word forensic comes from the Latin adjective 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 side 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 as a form of legal evidence and as a category of public presentation.
