Or another shot of him (edit: it was the same shot I posted before, removed).
Though I agree it's hard to tell given potential lighting conditions or maybe if he had gotten a tan. But I agree that the person initially reporting him probably thought he was Muslim. In other words,
even white people can also be misinterpreted as Muslims. Maybe less likely to occur, but it can happen.
