tigers at no fault

Recently, the news of 2 tigers mauling a person to death. So what happened? The person was a worker or cleaning at the zoo. For some reasons he climbed into the tiger area and swam past the moat. So that's how he got killed. The keepers came at once when the alarm of someone being attacked by the 2 tigers came and distracted them with whatever they could find. Throwing pails and using the broom sticks to distract them. After this news, many people who are newspaper readers wrote in. The put in all kind of stupid and lame questions such as why the tigers should be put down. First of all, why the stupid brain of their would think itis the tiger's fault? Someone entered their lair so the tigers could go at the "intruder". Second these beasts have killer instincts. While the zoo tried to put barriers to stop people from entering, they are only deterance. If someone wants to climb they could. Some sensible readers point out, people jump on the tracks of the MRT. So is it the train driver fault? Next time these lame post start to appear on the papers trying to act smart questioning, the poster need a smack on their pea brain for wasting time and resources on their useless questioning.
