The "Code of Silence" refers to an unwritten rule among certain groups, particularly in organized crime, where members do not cooperate with law enforcement or disclose information about illegal activities. This code is intended to protect the group and its members from prosecution and maintain loyalty within the organization. In popular culture, the term is often associated with movies and television shows that depict the lives of criminals, such as The Godfather or The Sopranos. It highlights the tension between personal loyalty and the law, illustrating the challenges faced by those who might consider breaking this code.
