Privacy advocates and musicians have rallied outside Madison Square Garden, pushing for a new law that would prevent facial-recognition technology being used at the venue and other public spaces in New York City.

Council member Shahana Hanif led the charge, declaring: “MSG and its CEO, James Dolan, have been flagrantly abusing biotechnology.” In January, she proposed legislation to ban such tech, citing examples of fans being tracked and restricted from attending games due to disputes with Dolan or his properties.

The issue gained traction after WIRED reported that MSG maintains a database assigning risk scores to celebrities and VIPs, some dossiers including race and sexual orientation data. The company has filed a defamation lawsuit against the publication.

At Friday’s rally were Brooklyn-based country musician Paisley Fields, representatives from NYC DSA Tech Action and Fight for the Future. Hanif’s “Ban the Scan” bill now enjoys 27 endorsements, more than half of the City Council. Members are in talks with speaker Julie Menin about advancing the legislation.

“People have been recognizing each other’s faces since the beginning of time—we just do it electronically,” an MSG spokesperson responded to the calls for reform.
