I was talking recently with a good friend of mine who works in marketing retail store loss prevention electronic systems. Apparently a technique commonly used by professional level thieves is the foil lining of bags/purses/coats etc. to mask the field from the inventory control tags; thereby evading the beeping at the door. In response, newer door systems are available which can detect the entry of the foil lined bags. They're basically just metal detectors and they also detect the entry of firearms. What a certain retailer does with this knowledge varies. Apparently most who actively pursue this sort of thing 'mark an exception' in the security control room and then an operator begins to personally follow this person's movements via camera. For those not carrying bags but who create an exception, the assumption is that they are carrying a firearm. I'm sure some legit ladies carry both bags and firearms. This system and issues are completely separate from the emerging RFID tags for loss control, inventory tracking, etc. I'm not sure how this would really effect our daily comings and goings. Certainly it could lead to harrassment of lawful carriers by store personnel. They could ask you to leave and you could refuse to patronize their business. My biggest concern is not that the corporate thinkers would not consider lawfully armed citizens in their planning for this technology, but that Joe Blow the Saturday night manager at the big box store may not be particularly well trained and could be a needless irritant. Any thoughts?
