The term "National Police" refers to a law enforcement agency that operates at the national level within a country. Its primary responsibilities include maintaining public order, enforcing laws, and preventing crime. National police forces often work in collaboration with local and regional police agencies to ensure safety and security across the nation. National police agencies may also handle specific tasks such as counter-terrorism, drug enforcement, and immigration control. They are typically organized under the national government and may have specialized units for various types of crime. Examples of national police forces include the Federal Bureau of Investigation (FBI) in the United States and the National Police Corps in Spain.
