Yes, but what about situations out side of the home? Vehicle, place employment, ect? If I was carrying that day the pistol would be in my waste band instead of locked in my gun cabinet.
Perhaps, but you were unarmed at HOME because you chose for it to be that way. Can't blame it on the law. More important that you learned something from your mistakes, such as the fact that he could possibly have been inside your home before you unlocked your gun. They don't always ring the doorbell first.
Where's the gun cabinet? In the living room where he'd have been breaking into it?
