This is horrible. RIP to the victims and I hope there aren't too many fatalies, wtf is going on in this world that somebody would bomb a concert when people were just trying to have fun... hopefully it was just the speakers that exploded but people heard gunshots.
Anybody making jokes about this is fucking vile. Imagine if somebody close to you died just because they were in the wrong place and the wrong time and just trying to enjoy a concert. You all make me sick.
