I am glad I don't own a gun. Half the domestic homicides are caused by the the family itself. How many stories do you hear about where a person broke into someones home and was shut by a hero that protected their family. Not many. How many stories do you hear about a father who killed his own family and them put gun on himself. TONS. No I am not that stupid. I just watch the news and I read. Huge percentage of domestic gun violence is caused by the gun owner or a close relative or family member or friend. Someone they know. A jilted lover perhaps. But not by criminals who breaking into your house to hurt you. Those things are few and far between. Yes there are serial killers and murderers. But those don't break into people's homes. They are smarter than that.
