A Texas school is to allow vetted teachers to carry handguns into school for the first time starting next term.
District superintendent David Thweatt:
We have a lock-down situation, we have cameras, but the question we had to answer is, ‘What if somebody gets in? What are we going to do?” he said. “It’s just common sense.
It certainly adds a new dimension to homework policy and lesson plans.
Think for Yourself 
As a teacher, I could not work at a school where the teachers carried guns. That is not the type of environment kids needs for learning.

I am still learning to teach. It is hard enough for me to get the students to understand that heat and temperature are not the same. For me to learn how to defend them in a gun battle in addition to teaching would certainly put a damper on my enthusiasm.
There is an armed police officer assigned to the school where I teach and that did take me aback. I think it would be distressing to work at a school where guns were commonplace, both for teachers and students. I doubt the superintendent in the article would be able to convince me that more guns would make everyone safer.
