There were some facts in there, like yes there are 3 different sets of laws, Federal, State, and Tribal (different for each state and each tribe). They do often overlap or conflict. The Feds usually have the ultimate say. When the State tries to infringe on my local Seneca tribe rights by trying to charge them tax on tobacco or gasoline the Indians have occasionally shut down the NYS Thruway with burning tires until the State relents (the NYS Thruway runs through the Seneca Cataraugus Reservation). The Seneca Nation has some unique rights like freedom from taxation (they don't pay NYS sales tax, and sell tobacco and gasoline tax free). The Senecas had legal casino gambling for decades before NYS sold lottery. The Indians legalized weed several years before NYS, and licensed dispensaries on the reservations. HoF's dissertation went way beyond the facts into fantasy about synergy between the 3 sets of laws, or being able to slip between the cracks and get away with stuff.
