Sue sue sue! They keep phrasing this like the problem is that maybe the systems can be inaccurate as the primary problem. But if they were perfectly accurate their existence and deployment in this context is still a travesty. Supermarkets aren’t police, they have no right to do this, if I go shopping I’m not volunteering to participate in a lineup. These types of systems are some of the more egregious examples of a larger trend of accepting private companies taking on powers that are only supposed to be tolerated when wielded by the state, I don’t want to live life like an inmate, offering you my custom should not be rewarded in this way.
