Perhaps no tourist attraction in the world underlines our ongoing fascination with organized crime more than The Mob Museum in downtown Las Vegas. Opened in a former courthouse on February 14, 2012, the $42 million museum shines a light on how criminal enterprises have impacted society in the United States.

Exhibits here include the wall from the Saint Valentine’s Day Massacre, a crime lab, and a speakeasy. There’s also the chance to wander a century-spanning "hall of shame" and learn about successful efforts made to bring down the Mafia with wiretaps and bugs.
