Basically she just shot herself on the foot.
I don't know how much the rest of you know about muricanese culture (I'm an expert), but defense and freedom are huge parts of it. It's not like it is in Japan where you can become successful by being honorable. If you screw someone over in murica, you bring guns to yourself, and the only way to get rid of that offender is more guns.
What this means is the muricanese public, after hearing about this, is going to want to purchase more guns, and will get more freedom. This is HUGE. You can laugh all you want, but she has risen an entire market with this move.
Lady, publicly apologize and use open carry or you can kiss your business goodbye.
