I agree that this is true. But once one unloads a gun, he3 no longer needs to treat it as a loaded weapon.
I have heard about a lot of gun accidents. Usually they are of three types: children playing with a gun, idiots fooling around, often drunken idiots, and "gun cleaning accidents". I doubt that anyone has ever been shot with an unloaded gun,and from what I know about guns, it does not take a major amount of skill to unload one.
