RCFP: Golden Globe "middle finger" incident

Darren Aronofsky gave his middle finger to actor Mickey Rourke who was on stage accepting an award during live television. The incident happened during child-sensitive hours (6 a.m. to 10 p.m.) which violates FCC rules. The FCC is in a "transitional period" and does not know if they will action against NBC. 

I don't exactly understand how it is completely fair to punish/fine a television station for airing the actions of someone else on LIVE television. NBC had no control over Mr. Aronofsky. I do believe Mr. Aronofsky's actions were offensive but telling people they cannot flip someone else off is violating our 1st Amendment. If people had to sign a contract stating all the rules and regulations before they attended an event maybe it would make them more conscience of their actions.
