Not everyone is an expert on which sharks are g0od and bad.
I don't know the difference between a coral and a king snake. They are the ones with white red and black rings on it. They are just in different patterns. If I find one in the yard I am getting a HOE from the shed. The only good snake for me is a dead one. I can clearly see how the same would apply for an unexperienced diver, as so many are, and can make the same decision. If it was a blatent attack by the diver against nature, the knife probably would not have still been there.
