I think it is a good idea but, ER visits are very expensive. Lawmakers will balk at the idea. If you required a mandatory visit to a doctor it would have to be immediate or the abuser might be worried enough to do something drastic before the doctor's exam.
How do you balance the right to privacy and the need to protect these innocent victims? Maybe free healthcare for children with mandatory screenings? Maybe we just need (as a society) to be more aware and less afraid to speak out. If CPS is not held accountable this will happen again. We need much more extensive involvement when people report their suspicions. I also think that step-fathers/boyfriends need to be monitored somehow when there are young children in the house. It just happens too often, every freakin' day I read this $hit.
Educate yourself people, know the signs.
