Probably "This looks like the statue of liberty". Unless I saw the photos side by side, I doubt I'd notice that the Vegas one was not legit or that it looked any different from the real one.
In another article I read they quoted the person in charge of the decision, who said that he found it on a stock photo site and just like that "newer take on Lady Liberty". Maybe he just thought it was from a different angle or was photoshopped to have softer features?
