Final answer:
A babysitter neglecting to supervise a child resulting in drowning can be considered negligence, possibly leading to severe legal consequences such as manslaughter or child endangerment.
Step-by-step explanation:
If a babysitter leaves a 3-year-old child unattended at a swimming pool and the child drowns, this could be considered negligent. Negligence is a failure to take reasonable care to avoid causing injury or loss to another person. In this situation, the babysitter has a duty of care to protect the child from harm, and leaving a young child alone by a pool is a breach of that duty.
Furthermore, in such a case, the negligence could lead to serious legal consequences, including charges such as manslaughter or child endangerment, depending on the jurisdiction's laws. Supervision around water is crucial, as drowning can occur quickly and without noticeable struggle, contrary to what some dangerous myths about drowning may suggest. It is important to always supervise young children closely around water to prevent such tragic incidents.
