Before September 11, 2001, the song "God Bless America" was played in Yankee Stadium only on holidays. But since mid-October of 2001, it has been played before the bottom of the seventh inning at every game. It seems like that would be punishment enough, but George Steinbrenner has taken the punishment a step further: While the song is being played, fans are not allowed to leave their seats.
"Not allowed" means that off-duty uniformed police officers, ushers, security personnel, and aisle chains are used to restrict the movement of patrons. One end of each chain is held by someone to prevent the chaining system from being a fire hazard.
A spokesman for the Yankees said that the system was put in place after hundreds of fans complained that other fans showed a lack of respect for "God Bless America" by not observing silence while it was played. The spokesman also said that no one has complained about the system. The Mets do not restrict movement during the playing of patriotic songs. However, several other teams do, but with personnel only, not chains.
The New York chapter of the American Civil Liberties Union has stated that since Yankee Stadium is private property, the restriction practice is not illegal. However, if someone is arrested for disobeying the rule, the ACLU would consider stepping in.
