Re: maybe she should have stuck to the housewares aisle
The salesman is an idiot. It is NOT illegal to buy a gun for a spouse or child who is legally allowed to purchase for themselves. A straw sale is when the gun is purchased for someone unrelated and/or NOT legally allowed to own, with knowledge of that condition.
He had NO cause for suspicion of a straw sale if she specified this, and as her husband was with her.
You are what you do, when it counts.
