You haven't been following the trial very well, he did use it in self defense. Why don't you get a gun and put it on your dresser and wait for it to jump up and shoot you all by itself. Guns don't kill people, people kill people. There is much more to these events than you can say is evidence to support your OPINION!!!!!... Why don't you go to a range and get educated in the role that having a gun can play in your life, maybe you will save your own someday or a neighbor or a friend or even your own family.
