Marshals are law enforcement officers responsible for maintaining order and enforcing the law in various settings. They often work in courts, serving legal documents, providing security, and ensuring that court proceedings run smoothly. In some regions, marshals may also assist in apprehending fugitives and executing warrants. In the United States, the U.S. Marshals Service is a federal agency that plays a crucial role in the justice system. Established in 1789, it is the oldest federal law enforcement agency and is tasked with managing and transporting federal prisoners, as well as protecting witnesses and managing seized assets.
