Dennis Barrie, who also worked on other museums, developed museum. In 2000, the government sold the post office and courtroom for $1, hoping the building would be renovated and put to use towards the community. In 2002, a former mob attorney Oscar Goodman developed the idea of the museum, although his ideas were opposed to by the people affected by the mob. During tours, visitors can learn more about Las Vegas life itself, including the casinos, stories behind organized crime, prohibition, and the personal lives behind the mobsters. Artifacts from mobsters, including Al Capone, a gangster in the prohibition era, and Mickey Cohen, a gangster in the Jewish mafia, on on display in the museum.
At the museum, there are more than just exhibits to look at. You can interact with the artifacts, including an electric chair, listening to wire tapes, watching FBI interrogation clips, and look at images of gory, deceased mobsters.
