The article just seems to rest the concern on what we would call shoddy police and medical work. A dead child has a brain injury. SBS, Accident, or medical condition that should have never seen them released discharged from the hospital at birth.
When I interned with the Queen's DA doing white collar crime, we shared a floor with the special victim's unit and there was some training/recruitment educational spillover. I can recall with all too much vividness a prosecution training video 'explaining' SBS. Essentially, it related it as a misnomer. The 'examples' and standards were akin to Vaskidmark's case: " taken by the ankles and had the head swung into walls, the bathtub, and the commode."
SBS seems a sugar coated cover for the fact folks who otherwise seem like sane and regular members of society can 'flip out' and vent frustrations on the smallest and most vulnerable to deadly effect. I was present for the video confession of one such person. An at home computer programmer who killed his gf's infant daughter by swinging her by the ankles against the desk, wall, and floor. He concluded his confession with "my bad."
I think like most people, when I first heard about Shaken Baby Syndrome I had the human perception and concern of how I saw a lot of people playing with babies; a bit rough, whirring them around playing airplane and even tossing them gently into the air. Having been instructed on the special way to hold a baby to support their neck ect, I thought SBS could be an accident. Outside of some special circumstance (premature or other increased fragility) babies are as durable as a mother of 3 would have you believe. As long as they don't land wrong they bounce.
