I live in southern Arizona near a large Indian reservation. The reservation informally allows non-members like me to hike there as long as we follow tribal rules. One of those rules is no guns. As a law-abiding citizen, I go unarmed when I hike there. I do pack on adjacent BLM land, but in places it’s unclear just where BLM land ends and tribal land begins. I’m concerned about my legal status if I inadvertently stray onto the reservation while carrying and have the bad luck to have to defend myself against bad guys, like drug smugglers. Would I be subject to prosecution under reservation laws, or would Arizona’s self-defense laws apply? No one in this rural area seems able to answer. I’d appreciate an opinion from any legal minds out there. Thanks.
