Casinos are a big business, and they take in billions of dollars each year for their owners, investors, corporations and Native American tribes. They also provide jobs and pay taxes to state and local governments.

They are also more knowledgeable about security issues than unlicensed workers, and they can help protect patrons from fraudulent activities.
