During the course of the shoot, writer/director Taylor Sheridan was visited on set by Shoshone tribal leaders who astonished him with the revelation that, at that very time, there were 12 unsolved murders of young women on a reservation of about 6,000 people. Because of a 1978 landmark government ruling (Oliphant v. Suquamish), the Supreme Court stripped tribes of the right to arrest and prosecute non-natives who commit crimes on native land. If neither victim nor perpetrator is a native, a county or state officer must make the arrest. If the perpetrator is non-native and the victim an enrolled member, only a federally-certified agent has that right. If the opposite is true, a tribal officer can make the arrest, but the case must still go to federal court. This quagmire creates a jurisdictional nightmare by choking up the legal process on reservations to such a degree, many criminals go unpunished indefinitely for serious crimes.

It's not possible to freeze the lungs by running, even in extreme cold. Air gets heated by the nose and throat before it reaches the lungs, and the lungs themselves are continually heated by the circulating blood. You'd die from hypothermia long before the lungs could freeze.
