I was in a lecture 1 floor down from this 'occurance' when it broke out.
Apparently individuals of Arabic descent were snickering and showing (subdued) happiness at the footage of NY falling apart, only not subdued enough. I believe a number of good Aussie students took upon themselves to start the retribution. And it was severe enough to have the bulk of the Uni security needed to break it up.
Wish I was there actually. And not as a bystander...
