Lawmoe: "If there are reports on abuse in the past, may I assume that they were also investigated? Since nothing occurred, may I also assume that they were found unsubstantiated? May I also assume that you continued to live with your spouse and he had access to the children and may have cared for them when you were unavailable?"
You know as lawyer that unproveable in court is not the same as never happened. a lot of people make the mistake of not reporting incidents the first time they occur, often most violent time, because they are in shock. One abuser I know only hit the kids on the back so the welts would not show in school. You really should get an education on domestic violence.
