A coupla years ago out here, a nurse administered some medication by mistake, that led to the death of an infant. It was a tragic mistake for sure. The subsequent investigation turned up absolutely nothing as regards the nurse, except that she made this one mistake. It did however, turn up some pretty glaring flaws in the hospital's regimes. In any case...the nurse lost her job - and her profession.
Alas, the $Millions paid to the child's parents and their lawyers, weren't sufficient. Their child died, so someone must pay with their life. At the very least, they wanted to see that nurse thrown in jail for decades. They eventually hounded the poor nurse to suicide.
