Tribal governments,sovereignty, and the US government ( Stephanie Gronewold)

When reading this chapter my eyes were opened to how badly the US government treated the Native Americans. The US government gave the Native Americans the right to govern their own people and yet as time went on they have to interfere. When reading this do all tribes and communities have their own laws? Would it not be better if they all came together to form one supreme law? That way when dealing with the US government they would have more power. I feel that the things that happen on the reservations should be handled by the laws of the Native Americans. When laws are broken outside of the reservations they should be handed by local authorities. I feel the same is true if we break laws on the reservations. I have an issue with people getting taxed twice for the same thing and being charged twice for the same or similar offense.
I believe that the US government should let the Native American people govern their own people without the government stepping in. When the government interferes they always seem to benefit from the Native Americans. Some Native American tribes are trying to use casino profits to support themselves but there just is not enough income. I don't know what the answer is but somehow we need to find a solution.
