A Law Late In Coming, Not Enough, But Glad It’s Here (Thank You Governor Mark Dayton)
In my experience, in the cases above for example, none of the people in the child protection system recommended bringing charges against the perpetrators because the damaged very young children would have had to testify in these trials (and children make terrible witnesses as they are easily confused and their testimonies are almost always useless).
As the guardian ad-Litem on these cases, I was told by the judges & my superiors that my choice was to remove the children from the home (and away from the perpetrator) with good odds of winning the long term safety of the children, or to go to battle with a 5 or 7 year old as my witness against a legal system stacked against the child.
