Which department's primary role is to prosecute criminal cases within its jurisdiction?

The primary role of the District Attorney's office is to prosecute criminal cases within its jurisdiction. This office is responsible for evaluating evidence, making charging decisions, and representing the government in court during criminal proceedings. The District Attorney serves as the chief prosecutor and oversees a team that may include deputy district attorneys who handle various cases ranging from misdemeanors to serious felonies. Their work is essential in ensuring justice is served by holding criminals accountable and ensuring due process is followed in the legal system.

In contrast, the roles of the police departments, such as Fullerton Police and Buena Park Police, primarily involve enforcement of the law, conducting investigations, and providing public safety rather than prosecuting cases. Meanwhile, the Sheriff - Coroner's office often has law enforcement responsibilities, including crime scene investigation and maintaining jails, but does not have the prosecutorial role that belongs to the District Attorney.
