On several occasions in my guardian ad-Litem work I was unable to bring charges against very dangerous child abusers and I observed their continued violent and sexual abuse of children over many years (I would venture one of these men is still having sex with very young children 16 years later).
Both the judge & my supervisor explained to me that in these cases, the choice was to remove the child or live through watching a child disintegrate on the witness stand and remain in the home with the perpetrator.
In Iowa’s case in the above article, the counties are out of funding and sending children back home to serious perpetrators of child abuse by simply erasing past histories. Every state does it, some are awful (Kentucky)
If there are no records, no one is accountable when terrible things happen to children.
