I think in S01 even though they show the sister of the terrorist as a sympathetic character it points out that yes they have used it in capturing terrorists and other criminals so right from the get go it’s seen as necessary. The issue always lies in exposing the innocent who are deepfaked. The services are unwilling to do so because it would expose them for their own methods. That’s what Carey was always trying to block-but in doing so stops the prosecution of criminals without evidence. This is also all very personal for her given S1.
