It is absolutely propoganda. It is misinformation used to turn shoppers against each other and use them to protect corporate assets. I can recall multiple videos of security agents being unable to physically stop shoplifters at the door, but another shopper(s) came to the rescue and joined the scuffle. Why the fuck is that anyone's business but the business in question? It's not. But they love that you think it is.
If you see someone stealing, no you fucking didn't.
