New ways for profits for big energy

CENTENNIAL, Colo. -- As soaring prices prompt huge increases in gas and oil drilling on public land, an ad hoc posse of state governments, Indian tribes and individual "bounty hunters" is charging that big energy companies are shortchanging taxpayers by billions of dollars.
