The Logistical Problems of Using "Weapon Detectors" For Subways

By IPVM Team, Published Apr 14, 2022, 11:01am EDT (Info+)

IPVM Image

In this note, we examine those problems in applying such detectors in subways and other high-volume mass transit applications.

For background, see Evolv Is Not A "Weapons Detector", It Is a Smarter Metal Detector and Evolv Detects Certain Chromebooks As Weapons.
