I live in a suburb of Houston and through my church I know of a couple school teachers that have concealed permits and carry in school. They are fine people with children of their own with whom I share a pew every Sunday. I believe that they have nothing but goodwill towards their fellow men, they simply are aware that there are crazy peoiple out there and their students look to their teacher for instruction, advice and sometimes for protection.
Here's why they don't have school shootings in Israel.
