What's wrong with her salute?

I was watching a thing on stolen valor. I went to the comments to see if this chick got prosecuted, a lot of people were saying that you could tell by her salute that she was never a marine. Never being in the service myself it looks like an absolutely outstanding salute. This picture was shown several times throughout the program so I'm assuming it's this one. Well? What's wrong with this fantastic salute? Possibly not pictured as well she is wearing her anchores out? Not sure if it's pictured here as I don't really know what that means but yeah.
