You're probably used to the presence of facial recognition cameras at airports and other transport hubs, but what about at concerts? That's the step Taylor Swift's team took at her May 18th show at the Rose Bowl, in a bid to identify her stalkers. According to Rolling Stone, the camera was hidden inside a display kiosk at the event, and sent images of anyone who stopped to look at the display to a "command post" in Nashville, where they were cross-referenced with other photos of the star's known stalkers.
