The news now is that the Tiger killed the person because he was taunting him. Bad move. Its never a good idea to tease and agitate an animal. By spreading these reasons, is the Zoo trying to avoid its responsibility? How come did they design a place that was physically possible for the Tiger to jump? To protect human lives is a bigger responsibility in a Zoo. Its not an open space or a Jungle where the risks are known and you sign up for. It was a bad move for that person to do anything to agitate the animal but the Zoo can not just escape from the fact that the den was not designed for the complete safety. Sick people.
