You have to have secure storage, you don’t have to use it. NFA may be different, I don’t know.
NFA items have to be secured in a business.
Gun stores with non NFA items have options depending on the level of security.
We had one store in a shabby building hit many times, poorer security that needed given the history of successful hits.
ATFE gave the store an option, upgrade the security, or lose your license.....
Or secure 1000 firearms each night...
They seriously upgraded their security.
The original posters incident could have been avoided easily by a narrow-er reinforced door, or properly placed bollards that do not allow a regular vehicle the width to drive through.
Or, a serious rolling barred/heavy link door at night capable of stopping a vehicle, like you see on pawn shops in the ghetto cities.
It is what it is.
The criminals in this incident are not local thugs, but an organized group hitting in Al, Ga, Tn, nFl area.
Reasonable precautions like a rolling chain door, or bollards would have prevented this. Too easy.
Building wouldn't be as aesthetically pretty, but, no pussy soccer mom van would have driven through.
