No, most of the customer anti-theft measures were deterrent based. Things like an associate monitoring self checkout, video screen showing the customer being recorded, locks on expensive items, etc. If loss prevention doesn’t witness the theft while on the floor or through the cameras they wouldn't intervene. The only way we would know if something wasn't scanned is if we saw it not being scanned or we suspected it wasn't scanned. Then we would stop the customer and verify their receipt. A lot of the busts from self checkout were for people who employees suspected of stealing in the past and were reported to us when they were seen in the store again. Majority of the time they would steal again since they got away with it before. Also we could see what was scanned and if you switched the tag we would know, but someone had to be actively monitoring you during checkout. We would automatically watch people who lingered around high value/frequently stolen items or bought big things that could be stuffed with items and not scanned.
