The home arena of the Dallas Stars has launched an investigation into a video that apparently shows four fans celebrating a goal with a Nazi salute. A spokesperson for the American Airlines Center in Dallas said that the arena has “zero tolerance for any acts of hate and/or discrimination, and we aim to ensure an environment for our guests that is free from disruptive behavior, including foul/abusive language and obscene gestures.” “We strongly denounce the actions that appear to be depicted in the video footage and are conducting an internal investigation,” the spokesperson said. “All fans and attendees are expected to adhere to AAC and, as applicable, NBA or NHL Codes of Conduct when attending events. Guests who violate any such Code of Conduct may be subject to ejection from the event without refund and, to the extent their conduct constitutes a violation of applicable law, prosecution.” A Stars fan, Courtney Ripley, told the television station she took a 12-second video at a game against Toronto in late December. It shows four fans reacting to a goal by appearing to raise and extend their right arms with a straightened right hand facing downward. The video gained traction this week on several social media platforms. A Stars spokesperson told ESPN on Thursday that the team is “fully aligned with the arena’s statement and working with them to find out exactly what happened.” Fan codes of conduct are prominent throughout the NHL. Every team has a scripted segment that is shared on their video boards, through their public address system or both, telling fans about their respective codes of conduct. The NHL also has a multipoint fan code of conduct that opens by stating, “The best hockey experiences happen in environments that are inclusive, safe and respectful.” The NHL said possible punishments for violating the code of conduct include ejection, suspension or a lifetime ban from future events. ...read more read less
