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.
Facial recognition confirmed he was a criminal and the scanner confirmed he had a gun! Of course we opened fire instantly. How could we have known it was just some guy with a water bottle?
We used advanced colorimetry to determine he was a criminal!
