I've just finished watching 'The Capture' which is a UK spy show about AI facial recognition and deep fakes, which takes all of this one step further. While it's fictional, they're show these central command type rooms with big screens that let a group of people on PCs manage automated tracking of people based on criteria they pop in, and various probability statistics of recognizing people. I've always wondered how it looks, all these thousands of camera feeds, when the authorities are searching and monitoring all those feeds.
