A prosecutor is a legal professional who represents the government in criminal cases. Their main role is to present evidence in court to prove that a defendant is guilty of a crime. Prosecutors work closely with law enforcement agencies to gather information and build a case against individuals accused of breaking the law. In many jurisdictions, prosecutors have the discretion to decide whether to file charges and what charges to bring. They play a crucial role in the justice system, ensuring that laws are enforced and that victims receive justice. Their work often involves negotiating plea deals and participating in trials.
