She must not be from Texas (a transplant). She obviously doesn't understand the way things are done in Texas and the character of the people who live there.
Prior to pursuing education as a career, my 8th Grade History teacher and wrestling coach had worn a highly distinctive, green colored, slightly flattened headwear item. He apparently had looked so good in it that he was invited to SE Asia to show it off. I still remember him going over his classroom rules on the first day of class. "If I catch two of you fighting, I'm going to break it up right there and keep you after school. At that time you'll finish the fight, and the loser will get detention."
The man became a role model for me, and eventually our High School principle. Now, some 20+ years later I still look him up when I get back home.
I have no doubt that he'd "have it in him," to ventilate any student shooter.
