Fortunately he was not killed by a human being

The natural injustice of the death of Steve Irwin, the daredevil conservationist who wrestled with crocodiles and dangled cobras but was killed by a relatively docile fish, has apparently motivated some of his most ardent supporters to wreak revenge.
Eight days after the documentary maker was killed in a freak encounter with a stingray while snorkelling off the north Queensland coast, and while his native Australians continue to mourn him, the authorities are investigating the possibility that the species that took Irwin's life is being targeted in acts of retribution.
