Chapter 2: Physical Evidence

The word forensic is derived from the Latin forensis, meaning “forum.” A town square or marketplace in ancient cities, the forum was the arena of discussion and disputation in judicial and other public matters. As society became more complex, disputes were argued and settled in formally organized courts. Today, the term forensic still applies and is used in courts of law or public discussion and debate.
