Target has one of the most comprehensive shoplifter detection systems in place. It rivals law enforcement in its ability to track thieves across all their stores.
I don’t believe the claim of shrink being the issue. There’s virtually no way it’s the root cause.
Walgreens tried to do the same thing (close stores and blame shrinkage) and even walked it back later (and that's not even pointing out they had an SEC filing a couple years before where they planned on closing 200 stores).
