No. All three victims were together when the tiger escaped, killing one of them. The other two ran for the cafeteria, which was closed. The tiger chased them. You make it sound like the two survivors didn't know the dead boy, when in fact they all arrived together.
Taunting does not matter. Sling shots do not matter. If the three men gave the tiger a wedgie and insulted the tigers mother it would not matter. The tiger escaped. That matters. He killed one man. That matters. The presumption to the general public is that the tiger can’t get out, even if its insulted.
Hanna wants to say that its strange that someone would go to the zoo on Christmas. Well then its strange that the zoo is open on Christmas.
The bottom line is that the zoo knows it has a dangerous animal. They are animal experts. They are expected to provide a safe environment. Taunting a Tiger is a bad idea. Its inhumane. Its morally wrong. But with all that, the fault goes with the zoo which did not provide safety. If the men jumped into the exhibit and were eaten, I would be on the zoos side because the men knew the zone of safety and they crossed it. Thats not what happened here. Zoos fault.
