I still don't understand. It looks like people were attending a concert of some sort when this happened?
I get Darwin references, but it's not like people dying by pokemon. This looked like a real tragedy.

@Athena I do not know if any bystander actually died, and if they did then the posting was in very bad taste. I was only trying to point the way to, Lizard of Ahaz's reference if you were not familiar with it.

@Fernapple
I appreciate you clarifying.
I think of the Darwin reference as stupidity dying off. Had these people been jumping on the balloon while it was on fire, it would make sense to me. As I said, the same goes for people who've died playing pokemon, because they walked into traffic or fell into manholes.
Here people were attending a festival not knowing this would occur (?) and could have happened to any of us.
