As a veteran, I thank your father for his service to our country and commend you for your loyalty & duty. My wife’s mother succumbed to Alzheimer’s and she too is at risk but it is a crying shame how the government now uses peoples’ infirmities as a lever to exert power over them.
If forgetting to pay your bills means mental incompetence I should have been sent up long ago. My wife forgets some small thing and she thinks it’s all over. We are being manipulated to believe that occasional lapses mean it’s time for the nanny state to intervene with an iron boot.
But their coming for your Dad’s guns - that’s scary & shows their real intent.
In my Dad's case, he really was found "incompetent" by a judge, because that unfortunately is what happens when someone else (me) states that he can no longer pay his bills. It doesn't mean that he would have been unsafe with a gun. However, that's how the government sees things. I fear that veterans will be afraid to seek mental help if they have PTSD or depression now, because then they would be added to "the list".
