Seeker,
I think you should report "the access to guns" comment to your principal.
I had a student in my class last semester whose behavior made me feel uncomfortable. It started with a disturbance in class, escalated to his running on the top of the chairs, and then the next week he threw a soda cup with ice across the room.
Fortunately, the Dean did speak to him.
You can't be too safe in today's environment.
Hugs,
EJ
