Which authority should the calltaker connect to for incidents on Ellis Island?

The United States Park Police is the appropriate authority to connect with for incidents on Ellis Island because it is a federal law enforcement agency responsible for protecting national parks and federal monuments, including those under the jurisdiction of the National Park Service. Ellis Island, being part of the Statue of Liberty National Monument, falls under this jurisdiction. The Park Police have the specialized training and authority necessary to handle law enforcement activities at the island.

In contrast, while the NYPD primarily serves the city of New York and could be involved in incidents occurring on land connected to the city, they may not possess jurisdiction over federal properties like Ellis Island. The FBI typically engages in federal investigations and would be more applicable in cases that involve federal crimes rather than immediate response situations. The New Jersey State Police covers state roads and interstate matters, but it does not have jurisdiction over federally managed land like Ellis Island. Thus, connecting with the United States Park Police ensures the correct response protocol is followed for incidents occurring on Ellis Island.
