No amount of evidence will ever overturn what we all KNOW IN OUR HEARTS
Not that I am advocating, but, if these nutjobs knew that all teachers and staff were armed, he would NEVER have shown up there. Same with the Aurora movie theater, that nutjob would not walk in a place where others are armed and start his crap. There is some validity in OP's statement. Not that there would be only 2 dead at the school, but that he would never have picked a school.
