You tried to explain yourself and yet your point still wasn't valid. This can happen anywhere at any time, to any venue, concert or artist. If anything it will be harder to sell concert tickets in general; not because of a Ariana, but because of fear and safety. "Her last tour was dangerous" you make it sound like every city she has gone to this has happened. Please shut up. Families are mourning.
