Zone of Death (Yellowstone)
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 the Vicinage Clause in the Constitution of the United States, a person may be able to theoretically avoid conviction for any major crime, including murder. == Loophole == The United States District Court for the District of Wyoming is currently the only United States district court to have jurisdiction over parts of multiple states, by reason of its jurisdiction including all of Yellowstone National Park, which extends slightly beyond Wyoming's boundaries into Idaho and Montana.
