The United States Commonwealth of the Northern Marianas
is made up of three main islands: Saipan, Rota, and Tinian.
At the end of World War II Tinian was the departure point
for the Enola Gay, which delivered the first Atomic bomb to Japan.
The Northern Marians have one Department of Public Safety. It has
two divisions: Police and Fire. Corrections used to be part of Public
Safety but became its own department in 2005. They also have
Ports Authority Police Force that patrols all of the islands
airports and seaports. Conservation Officers are also armed law
enforcement officers in the Commonwealth.
