Have a missed an explanation in prior threads why there is so much indian reservation involvement? Is it because of legal and criminal jurisdiction
Good question, sw. I think it has something to do with reservations not being subject to state laws, maybe not even many federal ones, due to the issue of "sovereignty". Reservations are under the Bureau of Indian Affairs, http://en.wikipedia.org/wiki/Bureau_of_Indian_Affairs
which has a history of corruption anyway, with profits from resources of tribal lands being siphoned off by government officials on behalf of themselves or their cronies. In addition, there is a great deal of competition for positions of power among the tribes themselves, due to the wealth involved in gambling as well as other projects which, by tribal sovereignty, allows the tribal lands to used to skirt laws that otherwise would apply. Also, I think I've read that tribes must be recognized by the government in order to "exist", and there's a lot of politics involved in that, too.
It's because of what kind
of jurisdictional autonomy goes with having sovereignty over land, specifically -- ie, tribal lands aren't answerable to state and local laws when it comes to stuff like land use and zoning. Hence, for one thing: Casinos in states that don't otherwise allow them. Where there's gambling. And one noteworthy thing about gambling is that it's just a little bit mobbed up, typically. State lottery systems, for example. Another noteworthy thing about the Cabazon tribe in particular is that it was practically created specifically so that there'd be land on which to build a casino. So there's that. And there's also everything that goes with that. Which -- at least theoretically -- is pretty much every very profitable major criminal activity of interest to both organized criminals and intelligence services the whole world over that you care to name. Such as drug and/or weapons and/or sex trafficking. Because if you ever want to see a return on your investment in any of those businesses, you do kind of need to control some legitimate and authorized enterprises that have very large amounts of very fast-moving cash money slopping in and out of their bank accounts. Otherwise, it just wouldn't be worth all the mayhem.
You could also maybe use a reservation to do some highly economical unenvironmentally regulated strip mining or....I don't know, whatever part of your weapons-manufacturing produced too much toxic industrial waste to do on state-regulated land. Or something along those general lines, anyway. I don't know enough about industrial manufacturing to know what the possibilities are. But do I assume that there are some.
Also.... Most reservations have tribal police who are at least responsible for the basic, everyday-type functions of law enforcement, and it probably doesn't hurt that they're not allied with or a part of the state and local criminal justice system in any way. I mean, it's not like people can commit murders free from all fear of prosecution just by enticing their victims onto tribal lands and killing them there. But in a more general and less dramatic way, whatever happened on the reservation would be handled on the reservation, wrt policing and possibly the administration of justice, too. And while I don't know, I do imagine that in geographically remote territories where most of the local population, including the police force, is both desperately poor and not very heavily obligated to a social contract that's never bothered keeping any of its obligations to them, it's probably easier to pay cops to look the other way while you do whatever mobbed-up and/or illicit-intelligence thing it is that you're doing on their land.
In short, while, it's purely speculative, that might be why there's so much Indian reservation involvement.
