    In total, there were 118 false positives — a rate of 4.29%.

    Earlier this year, investors filed a class-action lawsuit, accusing company executives of overstating the devices’ capabilities and claiming that “Evolv does not reliably detect knives or guns.”

    I mean, in terms of performance, I’d be more concerned about the false positive rate than the false negative rate, given the context. Like, if you miss a gun, whatever. That’s at worst just the status quo, which has been working. Some money gets wasted on the machine. But if you are incorrectly stopping more than 1 in 25 New Yorkers from getting on their train, and apply that to all subway riders, that sounds like a monumental mess.

      With how trigger happy police are, the false positives would lead to more deaths than they prevent. And police would claim it’s justified because the machine told them so.

    I saw a dude jogging up the stairs and his gun fell out of his hoody sweats. He looked at it for a second and the picked it up and put it on his hoody like it was his phone.

    5/7 best subway exit ever.

    The article links an article from March '24 talking about the introduction of these devices that contains this part:

    The scanner that Adams and police officials introduced during Thursday’s news conference in a lower Manhattan station came from Evolv, a publicly traded company that has been accused of doctoring the results of software testing to make its scanners appear more effective than they are.

    So they could never be trusted but were still allowed to proceed.

    Someone should tell NYC that it is unconstitutional to infringe upon a person’s right to bear arms.
