In the interest of balanced reporting, someone really could have noted in the post that the shark was "agitated" because a human was trying to make it into dinner for 30 or 40 minutes before attack.
I totally blame this on the fisherman, who clearly knew the law (once you identify the animal, cut the line) and still decided to go fishing for large animals on a holiday weekend in the middle of a crowded area. Then, he used being in that crowd as an excuse to ignore the law. His claim is that there were surfers and swimmers, so he didn't want to cut the line to release the shark - but for a full half an hour he gave no warning to any swimmers or lifeguards about what he had on his line. (and he wasn't alone - he could have sent someone)
In other news (to really keep this in perspective) . . .
In just 2013, there were 32 U.S. dog bite-related fatalities.
In 2012, in just California, there were 451 dog bites with legal claims.
That "72 unprovoked" number is global. According to the source, in 2013 California only had one attack. Globally, there were only 10 fatal attacks. The source site also says:
"The numerical growth in shark interactions does not necessarily mean there is an increase in the rate of shark attacks; rather, it most likely reflects the ever-increasing amount of time spent in the sea by humans, which increases the opportunities for interaction between the two affected parties."
I effing hate Shark Week.
