The perfect crime is the subject of many a mystery novel and practically every other Alfred Hitchcock film. It's a murder in a locked room or a poisoning that looks like a heart attack or something else seemingly implausible that does, in fact, have an explanation. Somehow, the crime is always unraveled, and the culprit is escorted off by the authorities.

If this crime was committed in the Idaho portion of Yellowstone National Park, however, being escorted off by the authorities would be exactly where the trouble begins. This is because a constitutional loophole could allow you to commit any crime there and get away with it. As this video from Vox explains, constitutional law is the friend of the criminal. Well, that and the fact that no one lives in the Idaho section of Yellowstone.
