A Girl Scout mom was barred from entering a Rockettes show at Radio City Music Hall in New York City after being identified by facial recognition software.

Kelly Conlon, who was traveling with her daughter's Girl Scout troop, was identified through biometric data as an employee of a law firm that is suing Radio City's parent company, Madison Square Garden Entertainment. According to a new MSG policy introduced in June, anyone involved in active litigation against the company is barred from entering any of its venues until the lawsuit is resolved.

Conlon was stopped by security guards who requested identification when she arrived for the early December show. Guards told her that she was unable to attend the show due to her employment.

Conlon is a senior associate at a New Jersey personal injury firm Davis, Saperstein and Salomon, the firm involved in litigation against MSG. She, however, is not involved in the case against the company. Her daughter and the Girl Scout troop were able to attend the show.

"I was just a mom taking my daughter to see a Christmas show," Conlon told NBC New York. "I did wait outside...It was embarrassing, it was mortifying."

According to an MSG spokesperson, the policy applies to all attorneys at the location to prevent the personal targeting of individual attorneys and since MSG does not always know the specific lawyers working on the case.

"While we understand this policy is disappointing to some, we cannot ignore the fact that litigation creates an inherently adversarial environment," MSG Entertainment told the press. "All impacted attorneys were notified of the policy, including Davis, Saperstein and Salomon, which was notified twice. In this particular situation, only the one attorney who chose to attend despite being notified in advance that she would be denied entry, was not permitted to enter, and the rest of her group — including the Girl Scouts — were all able to attend and enjoy the show."

Two weeks after the incident, the firm filed a complaint with the New York State Liquor Authority, claiming that MSG Entertainment cannot bar members of the public from its venues (unless they cause a security threat or are disruptive) due to its liquor licensing agreement. The SLA has opened an investigation into the incident.

A sign outside of Radio City Hall informs attendees of the use of facial recognition which MSG has claimed is used to ensure safety. The company did not share how they obtain the biometric data needed to identify people.

"They knew my name before I told them. They knew the firm I was associated with before I told them. And they told me I was not allowed to be there," Conlon said. "I don't practice in New York. I'm not an attorney that works on any cases against MSG."

Facial recognition technology has become increasingly controversial as the sophistication of the tech industry grows. The use of this biometric data has been criticized for violating privacy rights and contributing to racial bias and wrongful arrests when used in policing.

"The fact they're using facial recognition to do this is frightening. It's un-American to do this," said Sam Davis, a partner at the firm Conlon works at.

MSG Entertainment operates the "Christmas Spectacular" Rockettes show at Radio City. The company also hosts events including New York Knicks and Rangers games at Madison Square Garden and shows at Beacon Theatre, Hulu Theatre, and Chicago Theatre. The company also operates TAO Group Hospitality, which owns several nightclubs and bars throughout the world.
