A timely article.  A 91-year-old man with dementia just killed his 92-year-old wife in Anchorage, and doesn't know why.  I bet he wishes he had not had a gun.
Any household with a history or threat of domestic violence, or anyone with dementia in it, should not have a gun in it.  Woman of Alaska, pay attention if you don't want to be killed.  Don't hesitate, leave or at least toss out the gun if you feel threatened.
