A new wave of Middle Eastern gangs with no respect for authority who come out guns and fists blazing. The new Middle Eastern gangs across Australia are ruthless, violent and out of control. Police say they are becoming more and more brazen as they pull out their guns first and ask questions later. This episode takes an exclusive look inside the nastiest gang of them all, is given harrowing access to gang violence in our prison system and revisits some of the bloodiest murders to come out the conflicts.
