Ethnic Violence
I think the following paragraph should be removed from the article -

It has been suggested that the random violence was a delayed response to crime perpetrated by other middle easterners, such as gang rapes that occured in 2000 and 2002.

My main problem with it is that the claim being put forward is totally unsourced and unsupported. Yes, whoever put it in has provided an article from the Australian as a source. However, if you actually read this article, it doesn't say anything of the sort about the violence being some kind of delayed response to events in 2000 and 2002. In fact, it only mentions rape once. Here is the relevant section of the article -

In an article on this page nearly two years ago ("Don't turn a blind eye to terror in our midst," January 12, 2004), I argued that the increasing frequency of racially motivated attacks on young Australian men and women - including murders, gang rapes and serious assaults by young men of Lebanese Muslim descent - would rise dramatically throughout Australia. These problems remain widespread and have been documented in the ensuing two years.

So no mention of any kind of delayed response. Therefore, the idea is completely the POV of whoever wrote it, hiding behind a misrepresented source. It should go.
