I live in Wyoming where even Democrats own a dozen guns and it's a matter of law that most non-felons over the age of 21 can legally carry a concealed firearm without a permit. In short firearms are prevalent and common in this part of the United States.

With that said I have almost no worry about school shootings here. The schools do a good job of securing themselves, law enforcement takes any threat seriously, and our culture understands and mostly respects firearms.
