I disagree. The family is in the national spotlight because they put themselves there.Ms. Bevers, the primary victim, is in the spotlight. Considering the ages of the children, all the more reason to remain out of the spotlight and very simply attained by staying quiet. The idea that public opinion would be negative seems unfounded, as there appears to be absolutely no negativity focused on Ms. Bevers family of origin.
The over used phrase "grieve differently" is often used to rationalize behaviors that seem outside the norm. It is also important to consider the difference between anticipatory death and traumatic death.
We have no history (and are not entitled to history nor should we be asking for behavioral history). There seem to be a variety of professional folks on this forum. While some professional opinions seem valued and appreciated, others are not. I don't see the equity, which is most unfortunate.
