I doubt any ,or we would have heard about it just like we hear about six year old's killing their friends doing 'wrastling moves' and kids committing suicide after listening to marilyn manson and ozzy osborne.

I grew up screwing with alligators, poisonous snakes, sharks and other critters--I am still around them on a regular basis. So Irwin titillatingly fed crocs in his care, and was a bit dramatic about his rescues to sell advertising. Big deal. I think he was an asset to society.
