I love white tigers... I'm not surprised over the incident... cos in any case,whoever steps into an enclosure filled with dangerous animals, must bare the consequences... Still, the reason why the zookeeper entered the enclosure is a mystery.
I don't believe it's a suicide...
How the tigers react could be because they felt provoked in their territory, or they just wanna play... curious creatures you know?
But whatever people say about putting down these tigers, deserve to be shot in the head.

-_-
I just love tigers...
