I think some people are too quick with CPS. If they are doing things that are against the law, then it could conceivably be a police matter, but if I were you, I'd mind my own business just like he advised. He probably knows you're out to start trouble for his family and wants to keep you far away, as I would. I wouldn't give you the time of day if you started judging my parenting and nosing around my home.
