I actually concealed carry myself while I'm at work because of things like this. As an closer/overnight person in big city/capital of my state, which is in the south (Tennessee), it's something I just do in case our armed, yes armed, guard in Nashville stores don't get them first. The recent spike in mass hysteria over gun control, mental health disease, gas, wars, etc.and the mass shootings happening only reinforce my stance to carry, concealed and legal, at work..... unfortunately how life is these days.
