Larry makes a good point! Many tribes do not have such an agreement. I have never heard of a tribal court using their authority to prosecute a non tribal person, at least not successfully.

Tribal/county agreements are a whole new ball game though, we have to wait to see what comes of it. lots of room there for liability issues on both sides! I don't see whats in it for the county in these instances. Mostly a headache I would imagine.
