We had a big Tiger Shark scare a while back here in Hawaii. We had a series of very unfortunate attacks (a couple of which were quite tragic), and a corresponding desire by many in the public sector to respond by eliminating the "beasts" from the reefs. I vigorously tried to convey to people that removal of tiger sharks does not neccessarily equate to reduction in liklihood of attack (this is especially true because the probability of an attack is already so low that it cannot be accurately calculated). Despite our efforts, several hunts by the state were conducted, and numerous vigilante groups ended up killing a lot of tiger sharks. In one case, they did a hunt at a particular beach and caught four tiger sharks in one night. They went out again the next night and didn't catch any. A week later, a surfer was attacked at that same place. Although I do not have any data to support it, I suggested the possibility that removal of certain "home-turf" tigers might allow younger, perhaps more more aggressive tigers to come in an search for new food sources. I don't really believe this, but it sounds like there may be some evidence from white pointers in Australia. My brother has noticed that smaller whites appear to be more dangerous to humans than larger ones off the Farallon Inslands (California). > Anyway, we are entering their world.
