Government action has been needed for years to do something to stop the continuing gang attacks by lebanese, and it is the lebanese gangs who harass people physically. There may be russians/chinese/bikeys who are drug running, but there are not many actively harassing people out on the streets.
Some action needed to be taken, it wasn't, so there has been this public outcry, it came in the form of something truely disgusting, but the pain they feel is felt by many.
As for the complete and utter neo-nazi's, no one truely listens to them... if you go over to stormfront you will see the nazi's don't believe the crowd of people truely align themselves with their beliefs.
