Is the parent-shaming over the tragedy at the Cincinnati Zoo going overboard? Experts say the public needs to remember: this could've happened to anyone.

Police said Tuesday they are investigating the parents of the 3-year-old boy who fell into a gorilla enclosure at the Cincinnati Zoo and had to be rescued by a team that shot the 400-pound animal to death.

The Cincinnati Zoo's director on Monday defended the decision to kill a gorilla to protect a 4-year-old boy who entered its exhibit, noting it's easy to second-guess after the child was recovered safely.
