Fuck if someone would throw shit at the concert I would be attending I'd punch the shit out of that person before Axl could say STOP! Look at all the loss of energy of the crowd after they stopped the song, fucking sucks.
I think people are just throwing stuff at the band just because they know Axl will respond like this and he can threaten all he wants I think we and he all know they will not leave, it'll probably kill the tour + it's something 3 quarters of the global media is waiting for...
