I did Target security for a few months. Yes they build cases against people until it’s criminal action. It’s also not subject to one store. Rather I could just type in descriptions of people (apparent age, height, skin tone, etc) and it would search those descriptions. I could then match the person and add it to the running total. When I left I heard that some markets were rolling out an AI to track people. I can answer any questions if there’s anyone who want to know more.
