To expand Gunug's comment about Irwin's "careless treatment of his child:"
From an AP report about Irwin's death:
"His public image was dented, however, in 2004 when he caused an uproar by holding his infant son in one arm while feeding large crocodiles inside a zoo pen. Irwin claimed at the time there was no danger to the child, and authorities declined to charge Irwin with violating safety regulations."
I don't see the point of bringing this up at this time. It is easy to judge another person's actions from a distance.
