Petition to hold the kid’s parents responsible:
https://www.change.org/p/cincinnati-zoo-justice-for-harambe
Petition? How stupid is that? The zoo will be sued, with or without a petition. They will pay big. But if ya want to charge the parents criminally, good luck with that. Bottom line, a little kid should not be able to access or enter wild animal cages/enclosures. There is no debate here.
End of story.
