The key part your missing is that fact that he was attacked in the morning when sharks are actively hunting. You may be more likely to get in a car accident than being attacked by a shark but your probability is drastically increased when you go in the water when they are known to be hunting... Just like your probability of being in a car accident is higher if you go driving in a snow storm.
I live in NY and yes I go driving during snow storms knowing the risk... If I got into an accident I wouldnt say its the snows fault seing I'm the one who decided to go out for a drive. Same situation here... He knew the risks... he took em... and he paid the ultimate price... Why not put training off for a couple hours and not swim when its feeding time?
I never said I dont feel bad for the people who have to deal with the consequences... I said I dont feel bad for the man who made the decision to get into the water... Obviously it sucks for anyone else involved
