The public scared, then later the truth came out that the men tried to skip buying ticket and he went across the limited line. The animal has their nature. Once they are under threat, they will do the horrible thing. If the visitors behave themselves well and do as the tips, then the tragedy won’t happen. But still a lot of people scream and try to throw away the food to the animals, which do harm to the animals. It is everybody’s duty to protect animals.
