I am in no way at all defending this woman, because no one should ever think that killing an innocent little child is acceptable, but there really needs to be an easy way for Dr's, family or even the person themselves to get help when a threat or feeling of harming someone has been uttered. If she really did tell her Dr, days before she got her dirty hands on Jade, that she felt like she was going to hurt someone, why was she still walking around? Did the Dr not believe her? Did the Dr have no recourse to get her evaluated? Did BS refuse any help?
If she really did say that to a Dr, then Jades death was entirely preventable.
The mentally ill or even mentally fragile need places to turn to be believed and to get help the second they admit something like that. It wouldn't save all the children, but it may have saved this one.
