Baby-shaking prosecutions involve parents or guardians who shake their babies to get them to stop crying, usually, in a fit of rage. In one case, an Australian man was convicted when two forensic experts testified that baby-shaking was the likely cause of the child’s homicide. The man was imprisoned for nine years.
The controversy surrounds a “triad” of injuries that appear to indicate a baby-shaking homicide. These include bleeding of the brain, retinal hemorrhage, and swelling of the brain. In many cases, there are no external injuries to the baby at all. The belief that “triad-only” symptomology is at a 1:1 correspondence to baby shaking is now at the center of a hot controversy between prosecutors and scientists. Some forensic experts say that the triad automatically indicates shaking or abuse, while others are not so sure. The latter’s argument is gaining traction due to a recent article contesting the science behind such prosecutions.
The article specifically called out the two expert witnesses who testified in the baby-shaking case mentioned above. The scientist concluded that there was no finding of fact that implicated the defendant in that lawsuit to baby shaking, and the theory behind such prosecutions was based on studies conducted in cases where individuals allegedly confessed to the crimes. By comparing confessions to abuse, the experts were able to (by analogy) claim that the defendant was guilty of baby-shaking.
