Is she fair game?

After watching the movie Roman Holiday, starring Audrey Hepburn (Princess Anna), Gregory Peck (Writer; Joe Brady) and Eddie Albert (Photographer; Irvin), they are faced with a dilemma of to publish or not to publicize the quirk events surrounding a Princess.  The statement is made; " ...She is fair game..." implying they (the two male characters) should go forward and publish the Princess' activities.
   When posed with the question of Is she fair game? First we must define just what fair game is. My definition would be, when speaking of a girl, does she have a ring on her finger? If not, she is fair game. In other words, if a lady has not been betrothed to another, than she is fair game.
    With reference to the movie and the issue of printing the story & photographers; I would have to reply... Heck Yeh! After all, the Princess is a public figure. Her image in a public place is completely "fair game" based on those factors alone. Now, the movie is a romance, so Gregory Peck goes soft and decides to not go forward and write the story.  Not only is he out the five grand for his exclusive, he does not get the girl either.  FOOL!
   In conclusion - fair game has a broad definition as a whole, but may be interrupted very specifically when it comes to photography, especially when the image is captured of a public figure, in public.
