yeah i figured that part. however, this raises a few questions. one, who is paying the police officers that intervened? if they are NYPD, are they being paid by the city, or are the yankees paying the city to pay the officers? if they're being paid by the city, i would think that has some bearing - public-funded officers accosting private citizens at a private venue. also, assuming that there is nothing on the ticket or on the PA about having to stand still while God Bless America is being sung, it's unreasonable to think that people should know about this custom, let alone be obligated to follow it.
