This case appears to fall into the latter category. Nate Pachter told the Sun Sentinel he saw a group of people antagonizing the animal as the animal tried to swim away.
They were, he noted, "holding the shark by its tail. They were messing with it."
It isn't known if the woman who was bitten was among them - she is reportedly in stable condition in hospital - but we do know the shark paid an even more terrible price for it.
And today, the ocean is a little emptier because of it.
