super sad.
if travis has a history of actually telling his fans to do silly mess at his concerts he needs to be held accountable in some way
not to say he's completely responsible, but
if these people loved him enough to purchase a ticket chances are they follow him and anything involving him religiously and they've seen footage from his other concerts where he's encouraging fans to jump and leap and turn into daredevils for his entertainment.....
this sets an expectation that anything goes at his events and that its OK to act a complete fool, and it's even encouraged and welcomed for them behave like animals - whether that was his intent or not . it becomes part of the travis scott concert "experience".
this is assuming that this footage of him telling his fans to do crazy mess actually exists...i haven't seen it for myself but a lot of people are saying he has a history of it.
