No crime here, at least not in free states.
Could it be that the school is trying to stir up parents against the counselor, or at least make a mountain out of a mole hill? I wonder how someone knew she had a weapon? I would feel very uneasy carrying a weapon in CA due to this craziness.
When the school says she "made no direct threat" it leads one to believe she made an indirect threat. If she made no threat, they should have said she made no threat.
