If I perceive a danger it is real to me. Can you guarantee that I'll never see someone with a gun that places me in real danger?I'm sorry -- you'll have to demonstrate how simple possession of a gun harms anyone or places anyone in a condition of clear, present and immediate danger.And if someone perceives a danger from a stranger carrying a gun?When your action hams someone or places them in a condition of clear, present and immediate danger, sure.
Simple ownership and possession of a firearm does neither of these things
Your question indicates you know you cannot do this.
