It doesn't matter with gender, age, religion, political leaning, etc. The only one that does matter is mental status, as they need to regulate that. The right that hates spending, would rather spend money arming teachers. won't change much, besides the amount of children going to school, and the amount of people willing to be teachers. They have shit pay, benefits, and suddenly it's their job to be a western gunslinger. The guard hid because his gun doesn't protect much from an ar-15.
Another moronic liberal leftist canard; it's about money. You people are dumber than a box of rocks.
