Do you think that those who own and run casinos are criminals or conmen?
Not really. Most of them are just businessmen in a very profitable industry. The unfortunate thing is that some people can't control themselves and lose more than their fair share in the casino
Yes some of them are already rich people trying to expand their business structures. Criminals can't create a business since they are already wanted or have a record in the government. These criminals can only do underground business in the black market to hide their true identity.
