Since prayer and other things as don't mention Jesus at grad. etc, people don't have their heads on right, no less carry a weapon. They might use it on themselves. The fact that taking a defensive attititude against the ar15 that was used, posted on news that they will now be armed with the same assault weapon as was used to destroy lives. So now that will only cause more trauma, and only cause more stress, in remembering or even seeing that same AR 15. Not to smart to do, and not very concealing. Very traumatic, as remembering it, and causing further trauma. Wisdom has and is gone from the education system. Period.
Wisdom only comes from God, for it says, the foolish say, there is no God. NO they should not carry oc/ cc. Temptaion to shoot a student, as it is well known assaults on teachers, are very real, so either the teacher hits, out, or the student grabs. NOt Good.
