The Zone of Death is the 50-square-mile (130 km2) area in the Idaho section of Yellowstone National Park in which, as a result of a reported loophole in the Constitution of the United States, a person may be able to theoretically avoid conviction for any major crime, up to and including murder.
Sort of like “The Purge,” only it’s real and valid 24/7/365. One of the quirkiest legal loopholes of which I’ve ever read.
