I agree completely.
Most are accidental......although offshore whitetips are opportunistic feeders and bulls are considered to be dangerously aggressive.
In the case of many nearshore attacks, I think it is just mistaken identity.
I really get a kick out of all the "Shark Week" documentaries........scads of marine biologists trying to soften the shark's image and make people more "comfortable" and less afraid.
It all adds up to diddly ****. If you are in the water with sharks, you are at risk for an attack. Even a explorative nibble can bleed you out before you get to shore.
My message is counter to that of the marine intelligesia;
Stay the hell out of shark infested water, as it increases your chances of getting attacked.
Don't eat shark fin soup.
