Take the following as truth: Because of the new legitimacy Las Vegas acquired from Hughes' investments, established companies such as Hilton Hotels bought into the gaming business, and their influence helped draw a line in the desert sand between legitimate operations and mob casinos, where illegal skimming of profits was rampant.
Then the following statement: "The landscape of the casino business was changed when Hilton Hotels bought in, giving the industry more respectability." is true, false, or inconclusive?
