American Indians and firewater

Hey Dick, what about a bit of Sharia law then? Hey? How 'bout that?

From what I read, criminal laws in the U.S. still apply to Indian reservations (for the most part). You can't just murder someone on an Indian reservation and escape prosecution (there are specific laws regarding criminal activities on Indian lands but basically it's not a free-for-all and for the most part, Indian reservations are subject to state and federal criminal laws). However, Indians do have the right to set their own laws (prohibiting alcohol for example) but those laws aren't U.S. laws so enforcing them is either a tribal issue or worked out with the Bureau of Indian Affairs.
