True. The “Indian nations” as the Constitution refers to them have a large degree of immunity from state and local and even federal law, which is how they get to have casinos in the first place. Since Indian reservations are by definition tribal land and legally under the control of an Indian nation, they do not have to follow building codes.
The comedian Craig Fergusen of the Late, Late Show would have guests on that would talk about their upcoming show at some Indian Casino.
Craig said when he played them he always would say “Yeah - it’s a shame. Before the white man came there were casinos as far as the eye could see.”
