That was my first question when I saw men with bullet proof vests, helmets and semiautomatic weapons surrounding two banks in downtown Lander, a small town in central Wyoming. In reality, they were escorting an armored truck that was delivering millions of dollars in cash to banks around town. The cash came from the U.S. Treasury, and a few days later, thousands of Northern Arapaho from the near-by Wind River Reservation would flood into town to cash $6,000 checks. The checks were the government’s way of compensating the tribe for mismanaging its mineral resources for decades. For more on the settlement, the lawyer who saw the 37-year long battle to the finish, and the economic impact of the big influx of cash, see here.
