This happened in Britain, where some very unfit parents caused the death of their fourteen week old baby after inflicting violence on her that resulted in forty broken bones.
They got miniscule penalties and the mealy mouthed terminology used by those in charge of child welfare to justify how it happened is truly sickening.
I've seen much harsher sentences handed out to perpetrators of animal cruelty.
