These are the shallow end of the pool when it comes to what has happened when CPS gets involved.

The parents that care lose their children. They open their door thinking they have nothing to hide or fear. CPS finds something, anything, and it is hell to get your child back.

The parents that are actually abusive, keep their door closed and get a lawyer. And CPS is almost never effective and helping these children.

If you are an actual caring parent, leave the state if CPS comes knocking.
