Sainsbury's suspended live facial recognition at one store after staff wrongly ejected shopper Matt Arnold on August 6—the second such incident this year. Both Sainsbury's and Facewatch blame human error, claiming the system correctly flagged a suspect but staff approached the wrong person, while refusing to explain what the specific error was.

Why: If you ship AI systems with a 'human-in-the-loop' safety claim, this is a concrete case where that loop failed twice in the same chain: the AI vendor and the retailer both insist the tech worked, yet innocent people were ejected. The 99.98% accuracy stat is meaningless if the operational workflow around alerts is broken. Anyone deploying AI-assisted decision systems should design the alert-to-action pipeline as carefully as the model itself—specifying exactly what information staff receive, how they verify identity, and what escalation path exists before a person is confronted.
