I cannot down vote, and would rarely do so if I could, but I would here. You are blaming the hurricane on the butterfly. One guy pulled a trigger and killed someone.
I couldn't think of a more absurd reply to this incident. The whole point of swatting is to get the cops to break into your house and shake you up a bit. Anyone who's been online for the past decade knows just how trigger-happy police in America can be, and it was only a matter of time before something like this happened. This was a game of chicken fueled by a remarkable lack of empathy and conscience.
You don't get to wash your hands of the blame just because you didn't pull the trigger.
It is not even close to blaming the hurricane on the butterfly.
While it should not be possible for such a prank call to lead to a lethal outcome, it currently is entirely possible and realistic for such an outcome to occur in our society today. The perpetrator knew that was a very probable outcome, and used that knowledge to intentionally instigate such a scenario in order to achieve that outcome.
Just because he didn't pull the trigger doesn't mean he doesn't share any blame.
The world is not the perfect, logical, orderly fantasy-land you seem to think it is.
