A supermarket’s AI camera falsely accused a shopper of theft
“The AI decided he was a thief. The humans believed the AI.”
The Story
A Sainsbury’s store in London used Facewatch live facial recognition that flagged an innocent customer as a shoplifter, and staff asked him to leave. The store paused the system at that location after the incident; Sainsbury’s initially blamed human error in approaching the wrong person.
Why It Matters
Everyday retail surveillance turned a grocery run into a Kafka scene, with the machine’s word outweighing the human’s.
Evidence
BBC customer interview and Sainsbury’s statement.
