On one of the morning show (The Today Show, I think), one of the hosts talked about the incident where he took his baby in with the crocs. He said that this event shouldn't overshadow his life, and then they showed a clip of Irwin defending his actions. He came off as a weirdo, saying that "everyone is an expert" (like it takes an expert to know that you shouldn't take your kid into a crocodile pit) and trying to say that living by a busy road is actually more dangerous.
I'm not trying to beat up on the guy now that he's dead, but this sort of proves his critics right. Wild animals are dangerous and unpredictable. Irwin was a professional who supposedly knew what he was doing and he was killed. He's lucky his kid wasn't killed years ago.
