Final answer:
True, the violence of shaking that leads to shaken-baby syndrome is typically severe enough that observers would recognize it as dangerous. It involves symptoms like brain swelling and retinal hemorrhage due to the force used.
Step-by-step explanation:
The statement that the act of shaking leading to shaken-baby syndrome is so violent that individuals observing it would recognize it as dangerous and likely to kill the child is True. Shaken-baby syndrome is a severe form of physical abuse that manifests as a collection of medical symptoms, including brain swelling and retinal hemorrhage, which are the result of forcibly shaking or impacting an infant's head.
The violence of the shaking required to cause these symptoms is extreme and would likely be evident to onlookers as harmful. Tragically, common triggers for such abusive shaking include a baby's persistent crying, with potential stress factors like economic hardship, unemployment, and parental dissatisfaction often playing a role. It is estimated that annually, 1,400 babies experience serious harm or death due to shaking.
