I realize that people commenting are troubled by blaming the gun shop owner, but as an ex-AMMO troop in the US Air Force, when was the last time you heard of anyone ripping off our weapons?  Only way would be an inside job.  Weapons are stored in concrete re enforced buildings with heavy steel vault doors and intrusion detection systems.  Electrical fences around a warehouse that could easily be broken into by a truck is not secure and quite frankly IMHO negligent.
