1)Zoos should not exist in the first place. Animals such as tigers, elephants, lions, and gorillas should not be prisoned for the entertainment of humans. They should be roaming free. This would not have happened if zoos were banned.
2)The zoo was negligent for allowing the possibility of a child entering the habitat. There should have been a secondary barrier. I've seen this kind of stupidity before. One time, I was at Niagara Falls, and a child around 9 years old was sitting dangerously on the fence around the Falls in front of her parents. Had she toppled over, she would have rolled down the cliff and into the Falls.
3)The parents were possibly negligent. The father has a long criminal history. If properly supervised, this young child may not have fallen in.
4)The child is at fault for wandering away and falling in. Had the law of natural selection been allowed to be enforced, this child, who strayed from his parents and safety, and recklessly entered a dangerous, unknown area, would never have survived and his genes for dangerous behaviour would not be allowed to survive.
5)The zoo needed to take immediate action, but a tranquilizer gun should have been the first choice, with the gun ready for immediate action thereafter in case the gorilla reacted violently.
Either way, the gorilla was the victim of human stupidity from:
a)A society that prisons animals for their entertainment
b)Zoo officials that failed to eliminate a potential saftety hazard
c)Idiotic parents that allowed a todlder to be near a dangerous situation unsupervised
d)A child whose recklessness would have ensured its own demise in a natural setting
e)Zoo workers who did not consider using non lethal force to take down the gorilla
