Interesting subject
Which is more lawless, a Nevada or Indian casino.
The obvious answer would be the Indian casino, especially in my home state of California where really no one is watching the store.
What is not so obvious is although there is nothing stopping the Indian Casino from cheating you, throwing you out and just plain abusing you (sure you can sue them in tribal court????), the Indian Casinos that have mostly local players are very careful not to make a scene that would anger the locals and the local officials. While they take all your money they wish to appear good neighbors. At the same time the system is set up in Nevada where the casino, gaming (those who are supposed to be watching the store), the police (those who are supposed to protect you), the courts (those who are supposed to insure justice) all work together for the benifit of those who own the state of Nevada, the casinos.
So for the average conflict between casino and advantage player, I think the Indians have much better manners, but if the thing got way out of hand, you have recourse in Nevada if you want to fight all the way up the court system but no recourse with the Indians unless you believe a tribal court to be impartial.
It should not be close, but it will be unless the team of casino, gaming, police, DA's and many courts are fixed.
