My father has mild dementia/alzheimer's. He has seen two physician's (Neurologist and Neuropsych) and they have both recommended that he doesn't drive. Also, he has always had a gun collection and they have advised that it would be okay to have the guns without ammunition. If my father would drive and/or purchase ammunition for his guns and something should happen would I be legally responsible for his actions? I would appreciate some direction in this matter. I am new to this as my Dad's wife passed away in May 2020.
