My father has Alzheimer's and two guns, and revolver and a .22. He becomes angry easily these days and his wife and I would like the guns out of the house, however, he has them locked in his office and he has the only key. He recently told me about the guns, smirking as he told me he has plenty of ammunition. His wife asked him to give them to my husband and he refuses. I realize we will have to take these weapons but I am very afraid of his reaction and the possibility that he will obtain other weapons.
