She had hand gun classes, practiced at shooting ranges, hunted, was licensed to carry and carried every day.
The CC purse was a Christmas present from her husband.
She had her son and three nieces with her at Walmart.
Her son was in the cart while she left the purse unattended for a moment, probably thinking she was still carrying on body.
Someone who doesn't know where her firearm is located is irresponsible. That means she didn't know whether she had access to it if needed it for self protection, so she had no sane reason to be carrying in the first place. If someone tried to steal her purse and her child, she would have been surprised to learn that the weapon she thought was on her body was actually now in the hands of the person stealing her purse and her child.
