A District Attorney (DA) is a public official responsible for prosecuting criminal cases on behalf of the government. They represent the state or local jurisdiction in court and work to ensure that justice is served. DAs handle a variety of cases, from minor offenses to serious felonies, and are involved in the legal process from the investigation stage through trial. In addition to prosecuting cases, a District Attorney also plays a role in advising law enforcement during investigations and making decisions about whether to file charges. They may work with victims and witnesses to gather evidence and build a strong case for trial.
