Your choice of tools will affect your choice of work.

   If you buy a tool set, you will find uses for it. If you buy an egg beater, you will probably beat some eggs. Mold makers are for molding things, and if you buy one, you'll probably end up molding a few things.
  So, what of the gun? What is it used for? What was it created to do?
  Yes, protect. But, we are shorts-sighted if we suppose the use of a gun ends there. The gun might be protection to one, but it is used to kill by another.
  We often say guns don't kill, people do, and that is true, enough. But, think on the thought that if you buy a tool, you are influenced to use it for what it was meant to do.
   One person might reserve that gun in the back of the closet just for self defense, nothing more. But, as sure as any tool tempts its owner to use it for what it was meant to do, someone is going to be influenced to use the gun for a killing.
    Tools tempt. They tempt their owners to use them. And, they tempt their owners to use them for what they were created to do.
    More than any other thing, the purpose of some tools is to kill. Buy them, stick them in the closet, and tell them they are inanimate objects and can't possibly influence you to kill; That won't stop their influence.
    When the gun is the tool, violence is the trade.
