    We have this ridiculous system at my work. Knives are prohibited, but get through all the time, tape measures and water bottles really piss it off though.

    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.
