Yes, Coconut Island off Kaneohe is a hammerhead breeding ground but they are not known to ever attack anyone that is not already bleeding and in serious trouble. Most of the people that die off of Kaneohe (usually young Marines) die because they over estimate their water skills and not sharks. They may end up bit/eaten by a shark but it is not the reason they die. I lived there for many years. Yes, it is definitely bad publicity either way. Maui has a worst shark problem than Oahu in the winter when the whales are giving birth but I think this story has more to it than we know at this time.
