It's bad, folks.

The Garden is already known for its tight security. There is always a heavy police presence in part because the arena is in the heart of Midtown Manhattan and built above Pennsylvania Station, the nation’s busiest rail terminal. The station is patrolled by law enforcement officers and sometimes soldiers on alert for terrorism. Fans attending events at the Garden go through screenings that can include metal detectors, bag searches and explosive-sniffing dogs.

“We have always made it clear to our guests and to the public that we use facial recognition as one of our tools,” the company said in a statement.

High-tech surveillance by government is already common in New York City. The Police Department relies on a toolbox that includes not only facial recognition, but drones and mobile X-ray vans, and this month the department said it would join Neighbors, a public neighborhood-watch platform owned by Amazon. Neighbors allows video doorbell owners to post clips online, and police officers can enlist the help of residents in investigations.
