I'd have to know the statistics, but it might not be a 'problem'. If 70% of the mall shoppers are middle-aged white females, and 1% of them are shoplifters, and 0.5% of the mall shoppers are teen-aged black males and 50% of them are shoplifters -- sure, more middle-aged white females are shoplifters than teen-aged black males. It would still behoove the mall security to keep an eye on the teen-aged black males.
Again, this is just hypothetical. It would depend on the statistics.
I had a family member who owned a store. I would disagree with these statistics
