Malls and shopping centers have resources to protect their assets that many families don’t have; in the NYC metro area much of the population is disarmed. Our gibsmedats don’t have to fear armed victims.
Will mall security be able to cope with a flash mob of a hundred gang members who are willing to use violence against any security guard attempting to arrest any of their number?
Stores, supermarkets, banks, etc are where lots of cash are, and lots of expensive products which can be fenced later. Individual homes, not so much.
