Golly Gee Whizz Batman how solve smash and grabs and the local Bang Bang store .. Require reinforced concrete fronts perhaps vehicle stop stones or concrete blocks out front , like at any secure building Target has them in shape of Red Balls , this might be fighting for Gun Stores as well .. A two foot guard rail around the side and back of store . Prevent side and or rear access .. They need to be a bit more secure than a Clothing Consignment store they do deal in death after all be it for furry Animals, birds and or " Bad Gun Owners"  .. They are Local Gun depots not convenience stores.. we have to treat them as such . This is a place of business that sells weapons that can be used in a wide variety of ways . Some legal others not . It's my theory that many not all smash and grabs are insurance scams and the guns stolen are then sold on the Black Market . A win , win for everybody in the Gun business and the straw buyer then is bypassed entirely . Big Money for everyone
