Answer
Yes. As U.S. citizens, American Indians and Alaska Natives are generally subject to federal, state, and local laws. On federal Indian reservations, however, only federal and tribal laws apply to members of the tribe, unless Congress provides otherwise. In federal law, the Assimilative Crimes Act makes any violation of state criminal law a federal offense on reservations. Most tribes now maintain tribal court systems and facilities to detain tribal members convicted of certain offenses within the boundaries of the reservation.
