People come in & take whatever they want because they know Walgreen's has a "no contact" policy (they won't stop you). They shoplift everything. And Walgreen's doesn't rush to re-stock.
There are a lot of homeless and drug addicts in that area, but I don't know firsthand if they're the shoplifters.
I spoke to a police sergeant at the Walgreen's at Broadway and Polk, and he said it's pretty bad, and that even he has a hard time getting the shoplifters to stop.
