The place to commit a crime in the US and get away with it is known as the “Zone of Death.”
A 50-square-mile stretch of Yellowstone National Park lies in a sliver of eastern Idaho. While most of Yellowstone is in Wyoming, this geographical outlier leads to what has become known as the Zone of Death.

In this small zone is a legal oddity first proposed by Michigan State law professor Brian Kalt in his 2005 Georgetown Law Journal article, “The Perfect Crime” as noted in this Vox article. Kalt noted that under the Sixth Amendment, a person who commits a crime has a right to a jury trial composed of his peers from the state where the crime was committed and from the federal district where the crime was committed.
Herein lies the oddity. This small part of Yellowstone is under the federal jurisdiction of Yellowstone, including this part of Idaho. So the jury must be composed of citizens from Yellowstone and Idaho.
Yet, no one lives in the Idaho part of Yellowstone. A jury can not be seated.
