A legal loophole may have created a small 50 square mile slice of eastern Idaho which could be the venue for the perfect crime. People could get away with any major crime they commit there because the jury would have to be drawn from a district with no people. Krucoff and the new community crime blog "Blottered" report the details:
The federal district court for the district of Wyoming is defined as including all of Yellowstone National Park including 50 square miles in Idaho. However, the 6th Amendment requires that when a crime is committed, the jury be drawn from the state and district where the crime was committed. So by commiting your crime in the Idaho part of the park, the jury would need to be drawn from Idaho but also the district of Wyoming... population zero.
