It's not easy (not any easier) to shoplift because there are random checks. People are much less inclined to put something extra in the bag if they know they can be checked. The ones that do shoplift are not using the bags with a lot of other groceries to do it, they likely hide items in their clothing. In such a mode, it doesn't make any difference how and whether they check out any actual paid items.
