Protecting Incest Part 2

I investigate, CPS shuts it down. Again sidenote, they refused to look at the videos of my daughter and nieces talking about the abuse they suffered. Then they go to the house where it's happening and ask, "Did you do this?... Oh no? ok." then they open investigations on me for who knows what? They never tell me. But when i report, the wife calls me saying, "CPS said that you accused me of (specific accusation)." Does this happen everywhere?!
