I supplied the jrotc into the mix as a "what if" to the stated scenario. Our students weren't permitted to freely roam with the drill rifles, and if carrying them from a vehicle into the building/building to vehicle, it was a very short trip from the classroom to the vehicle outside. Air rifles were cased (plastic rifle cases) once we raised money through fund raising activities. Out of curiosity, which service branch of jrotc is at your local school?Just saying. My Granddaughter was in JROTC here. When not in drill weapons were cased, transported and stored by adult staff. Students were never permitted to wander the facility or campus with a weapon.
Doesn't matter any more. I see something suspicious at school or grocery 911. Monitor the situation and if necessary take appropriate action.
