This animal must have been terrified to attack people. I blame the zoo officials for not making the enclosure more escape-proof. It's difficult to keep great apes enclosed because of their extreme intelligence and ability to figure out escape routes in an almost human-like fashion. However that's no excuse and the zoo failed to protect this beautiful animal and the safety of the guests of the zoo. I hope they have to pay for all the medical costs. This is so wrong! A zoo should be a place of safety for the animals within it, especially rare animals like gorillas. A zoo should also be a safe place to visit regardless of the dangerous animals housed there.
