Eminent domain

There was a mom in news who killed her 4 month old baby by beating her against the floor for crying for milk. Wish we could take that moment back. Did she do it in postpartum depression? No wonder as soon as you enter the recovery room, the nurses ask you to promise that you wont shake the baby. But I guess not all people are in the know that the only way kids communicate is through crying or are not in their sane minds. we always wonder why theres always bad news in the papers and TV. While some may be disturbing, some might alert others. This can reduce some crimes. A scientist proposed that maintenace of order is better to reduce crime sthan aggressively going after the wrongdoers. Like Prevention better than cure? But what leads to the symptoms itself in the first place? I know a family with two children, where one turned out really good and the other got wasted. How did that work out differently? The elder was good at all things. Was the praise on him to the detriment of the younger's?
