She is going about this all the wrong way. I say anybody who just straps a gun on, that they are obviously so emotionally distraught about, is doing the wrong thing. And portraying the wrong message (big surprise there, right?). I would never recommend someone buy their first gun, have no clue about it, and be scared of firearms, then immediately move to open carry.
If she wanted to truly research properly, she would have rented a few guns, taken a safety class and then decided to carry when she knew how to use the gun (and how they actually work - a bullet in your fuel tank isn't going to "make the car explode"). THAT is a far more realistic and responsible scenario that matches real life gun ownership, not just strapping a gun to your side when you don't even know how it works. Beyond that, did she even ask the gun store owner how to use it? How to be safe with it? You don't get answers to the questions you don't ask......but hey, it's pretty obvious the article is meant to confirm her own biased preconceptions, so she'll do anything it takes to confirm them.
