During the 2013 presidential inauguration, a controversy arose: Did Beyonc lip-sync the national anthem? No definitive answer

During the 2013 presidential inauguration, a controversy arose: Did Beyoncé lip-sync the national anthem? No definitive answer was offered by those involved. What was clear was that the National Marine Band did not play during her performance, that a tape was played, and that those in charge of the event felt a live performance was too risky because the singer had not had the opportunity to rehearse with the band prior to her performance. Are there any ethical issues here? Does this action fit into any of the ethical categories? Could you offer any advice to those involved about the ethical issues?
