Hello, I posted once before and appreciate the helpful and thoughtful comments I got back. I live in Illinois and my parents live in Florida. Things have been bad with my dad since about four years ago and have gotten even worse. To sum up what I posted last time, he blew up at my wife and brother-in-law for, essentially, hurting his feelings and started saying awful things to me about both of them. He said he never wanted to see her again the last time I talked to him on the phone which was 9 months ago. I hung up and haven't wanted to call him back. There's been no contact since then, no birthday cards or calls, no Merry Christmas calls, no Happy Anniversaries, etc. He's always had a really short fuse and I've heard some troubling things from my cousins who have seen him in Florida. There have been incidents of him picking fights with strangers and threatening them. He always carries a gun and it's not too much of a stretch to see him using it against someone or having it used against him. On a more personal level, I'm in an interfaith marriage. My wife is Jewish and I'm not. It was never an issue but my father has started acting openly anti-Semitic. My cousin went into his home and says he saw a large portrait of Hitler on the wall over the bed. He's also been telling awful anti-Semitic jokes and challenging Jewish people he meets over their faith. I believe these anecdotes even though they're hearsay. They're consistent with what I've seen myself over the years. I feel his hate for my wife brought this dark side of him to the surface. With so much hate and bigotry in the world today I fear the worst may happen. When do I call the authorities? He is an ex-police officer and may be able to talk his way out of an uncomfortable position. On the other hand, he may get into a shootout with anyone who shows up asking questions. I know these are "what ifs" but I'm stuck and appreciate help. Thanks.
