The NRA tells us good guys need guns to protect us from evildoers. Maybe they were thinking about Christy Sheats, a staunch advocate of the right to bear arms. True, she had a volatile personality. A previous employer called her troubled. Houston police went to her home fourteen times in four years. She also had a .38 pistol, which she used to kill her two daughters during an argument. So here’s my question: Who protects us from the good guy with a gun and a problem? How many more innocents will be sacrificed on the altar of the Second Amendment?
