Then anything goes. If they want to be sovereign, let them provide for their own protections. I hope taxpayer money is not protecting them by providing sheriffs, troopers, etc.
If they want to murder, we can't do anything about it. They're not entitled to use our court system. Let them provide their own.
I agree. No HUD homes, no food stamps, no law enforcement. Speaking from a conservative perspective, it would actually be the most positive thing that could happen to Native Americans - people whom I am surrounded by right now, wearing Native pride baseball caps, playing with my son, and filling up my classroom. Soveriegnty is good for people.
I also taught on a reservation for a year. One of the Natives there told me that there were three generals who destroyed Native culture - General Custer, General Grant, and general assistance. Native people can easily rise to the occasion; I see it here, where Native people build a home by cutting down a tree and milling the lumber, not depending on welfare. Of course, some Natives do depend on welfare, and they are sad cases.
The Lakota people have a chunk of land that is equal in size to the Netherlands or Belgium. That's enough land for prosperity. The rest is their choice.
