Topic - U.S. Park Police

The United States Park Police (USPP) is one of the oldest uniformed federal law enforcement agencies in the United States. It functions as a full service law enforcement agency with responsibilities and jurisdiction in those National Park Service areas primarily located in the Washington, D.C., San Francisco, and New York City areas and certain other government lands. In addition to performing the normal crime prevention, investigation, and apprehension functions of an urban police force, the Park Police are responsible for policing many of the famous monuments in the United States and share law enforcement jurisdiction in all lands administered by the Service with a force of National Park Rangers tasked with the same law enforcement powers and responsibilities. The agency also provides protection for the President and visiting dignitaries. The Park Police is a distinct unit of the National Park Service, which is a bureau of the Department of the Interior. - Source: Wikipedia
