Using a gun can bring purpose to owning it 

   Motive and opportunity are elements of crime. I wonder on guns, and on motive -- how we buy guns for a purpose, and how they have a use. Do we not suppose this can lend to the motive? Should we not consider that once a person has a gun, they might search for reason to use it? So, I suggest owning a gun can be in and of itself a motive for using a gun. If buying a gun comes with a purpose, then using the gun can bring purpose to owning it; it can bring fulfillment to having purchased it.
