Villawood riots

I regularly watch the TV show Border Watch.  Anyone entering Australia has to have the correct visas and if there is the even the slightest problem the person is usually sent back to where they came from on the next available flight.  Therefore, any persons responsible for the destruction of government property should have any applications for visas denied and promptly sent back to where they came from.  If they refuse to name their country, then they should be sent back to Indonesia.  I read a very good comment on the 3aw website that likened these people to thugs "who kick your door in, sit on the couch all day watching TV while you work, then complain about the food in the fridge".  Meanwhile there are thousands of legitimate refugees sitting in camps around the world who have done the right thing, gone through the proper channels and after years of despair are still waiting.  Why aren't we helping these people instead of the illegals????
