New York City Mayor Eric Adams may think that all those who aren't as big as him don't have as much.

After a mass shooting event in a Brooklyn subway station on April 12 led to 23 people injured ( miraculously, no one was killed ) ears are perking up when he says he would want to see gun surveillance tech installed in hundreds of city subway stations.

Adams told WNYC that his office has been looking at technologies that don't require people to empty their pockets. The devices are not visible. He said that the city is looking to do a few pilot projects to see the full use of it.

The mayor is a supporter of facial recognition tech. Other cities like San Francisco have banned the technology, and studies have shown that similar policing systems can be unreliable and more than a little problematic.

New York City's subway system is one of the largest in the world, with 472 individual stations and a track that is connected to the rest of the system. The mayor's office doesn't control what goes into subway stations, which is overseen by the Governor of New York.

It isn't like the MTA is known for its work. The organization has been criticized over a security camera that was down during the Tuesday attack. The chair of the MTA tried to hide the fact that there are 600 cameras on that line that can tell where the alleged shooter came from. MTA officials have avoided giving more information about the state of the system.

Lieber said that they were looking at technology that wouldn't be intrusive, and that they were not going to create an environment where people can't go about their business. Our public square is here. The sacred public space in New York is what makes it possible.

The mayor has not said if they would have to install this technology in every single station, but he noted that the alleged attacker entered the subway at Kings Highway Station in Brooklyn before opening fire five miles away from the 36th Street station. In the aftermath of the subway shooting, many people used other transportation methods to get around out of concern for their safety.

Adams mentioned last month that he wants to bring gun detection technology to city schools.

The American Civil Liberties Union criticized Adam for his promise to end gun violence. The non-profit's senior policy counsel referred to Adam's policies as a return to broken windows and stop and frisk policies.

The Mayor's plan is filled to the brim with fear-based misunderstandings of what keeps communities safe.

What is this proposed gun detection tech?

The systems the self-proclaimed Mayor of Swagger is talking about are already in New York. The Museum of Natural History, Lincoln Center, and the Met are some of the locations where this tech has been piloted. The tech from Evolv Systems uses artificial intelligence and modern sensor technology to detect weapons on people without them having to stop.

The earlier version of these systems malfunctioned during a demo in Los Angeles, before anyone had the chance to use them.

Representatives of Evolv have not yet responded to a request for comment.

During his most recent media appearances, the NYC mayor has not specifically referred to Evolv, but he did say that his office is excited about full implementation.
