Both the "locks away guns, guns are always empty except on the shooting range or hunting, safety conscious" person and the "gets drunk every evening and sleeps with a loaded gun under their pillow" person are actually totally safe as long as they uphold the number one rule of gun safety: "The barrel of a gun may never be pointed at a person". Super hard to shoot someone unless you are Angelina Jolie or James McAvoy or one of those bullet ricochet superheroes. Of course it's a useless rule since it is simply stating the obvious. But that doesn't seem to stop people from repeating it.
