Presumably the data shows that petty shop lifting is a fact of business for big box stores and that the level of petty shop lifting goes up and down with staffing levels on the store floor.

The shoplifters are still the ones to blame for the shoplifting, but it's not entirely unreasonable for the town to demand some level of performance from the store rather than happily providing expensive police to deal with a problem the store could handle with cheap employees.
