While I agree that this technology is a problem, what privacy laws/regulations would you suggest? The problem with coming up with reasonable ones for this sort of thing is that the customers are in a public place. Are businesses not allowed to record on their property and analyze those recordings? What about a security guard spotting someone who shoplifted last week? Or a business tracking credit card numbers across stores? In order for things to be different, the policy makers need reasons to draw lines between this and examples like the above that most people would agree businesses can do. Here, accuracy helped be that reason, but it’s only a matter of time before the models are more accurate.
