SAN FRANCISCO — Don't yell obscenities, don't flip the bird — and don't even think about insulting anyone's mother.
The San Francisco 49ers and the NFL have adopted extraordinary security measures for Sunday's NFC championship against the New York Giants after New Orleans Saints fans complained of harassment by unruly 49ers faithful last week.
Undercover police will be dressed in Giants' garb and on the lookout for nasty fans. Giants ticketholders will be handed a card as they enter Candlestick Park with details on how to contact police if they feel threatened. And more security cameras and undercover police officers will be in place to identify abusive fans.
Season ticketholders have also been warned to follow the NFL Fan Code of Conduct: no foul or abusive language or obscene gestures and no verbal or physical abuse of opposing team fans.
The nail-biting 36-32 win last Saturday for the 49ers was the team's first playoff game in nine years, and a raucous crowd was on hand to enjoy the victory at the expense of the Saints.
"I apologize for any rudeness that may have happened," San Francisco 49ers president and CEO Jed York said. "I think you saw 49ers fans who were very excited about hosting a playoff game for the first time in a long time."
Those fans were so excited that they ruined the day for a shaken Don Moses and his two teenage daughters. Moses, a longtime Bay Area resident who is from New Orleans, said they were wearing the Saints colors and prepared for some good-natured ribbing.
Instead, he tells a horror story of fear and humiliation when his daughters asked him why he didn't do anything to stop the hulking 49ers fans who yelled vulgarities and threw footballs at them, screamed in their faces and called their mother a whore.
"The hostility and threats of violence were a constant throughout our experience," Moses said in a letter to the San Francisco Chronicle, one that launched some soul-searching by city officials and led to some 49ers fans to apologize on behalf of their city.
"Every other word from dozens of fans around us was an f-bomb shouted at the top of their lungs," Moses said. "There were seven or eight large 30- to 35-year-old guys directly behind us who cursed and threatened us the entire game." He turned to ask them to tone it down in front of his girls and they yelled: "Do not turn around again! Do not ever turn around again."
He was afraid that if the fans saw him calling or texting security, the men would harm his daughters.
"Every 49ers fan, the team and its owners should be ashamed and embarrassed to wear the red and gold today," Moses wrote in the letter published Tuesday. "They won the game but are losers in every other way."
NFL security director Jeff Miller told the AP that if the security cameras or undercover police catch such abusive behavior by fans on Sunday, they will be yanked from the stadium.
"We'll be looking early on to identify people trying to do those things in the parking areas and take action to remove them," said Miller, who will be at the game. "We're not going to be warning people inside the stadium. They will be removed."
