You think Death City has its own independent government?

I mean, the city seems to be pretty far away from the rest of society, I doubt it's recognized as a city in the United States, or even just the state of Nevada. Then again, it has been a hot minute since I've watched the anime or read the manga, so I'm not sure if there were any significant interactions between Death City and the rest of the world. Their operations are usually just a bunch of isolated incidents that would honestly bring about the military or something if it was brought to light to the rest of the world in any capacity. So it has to run independently of federal and state law, right?
