Just looking for some input on a recent incident where my elementary aged son may have taken a few rounds to school, a couple days later a school "resource" officer comes and talks my son and the principal and questions my son about my house, a safe, etc. and informs him of the dangers of ammo getting hot in his backpack and blowing up. My question is to the legality of questioning about my house without my consent or presence. Any input is appreciated. Thanks
