I sincerely hope it is documentary and not staged, because if it were staged it would say nothing positive about the photographer. That said, I voted that it is staged, because I would hope that the person depicted in the photo did not in fact share those opinions expressed by the flag and the newspaper headline.
+1 to the opinions expressed that it comes across as a tasteless attempt at generating shock value, sadly through cliched hackneyed tropes. NOT that I'm encouraging exploration of other forms of shock like violence either. And enough with the coy games. Just out with it and say what you're looking for.
