This enrages me - the animals should definitely be protected from punks like these. We can't afford to lose any more tigers. I think the boys got what they deserved. If their friend that was killed wasn't taunting her, then his death is these brothers' fault as well. I've only been to zoos for school and work, and I always see boys & men taunting gorillas and the big cats. There should be guards on duty at these particular exhibits and guys like these should be ejected from the zoo immediately.
