This story of the Sydney police working with Asian shopkeepers to smash a protection racket is very encouraging. Ethnic gangs of various sorts exist in Australia (as everywhere) and they mainly get publicity when they terrorise or harass people outside their own ethnicity. However, the vast majority of their victims are people from their own ethnic communities, who often are not able to receive proper police protection because the police do not have contacts in the community, and do not understand the language and/or culture of the victims of the crime. Obviously, such people are entitled to the same help from the police as anybody else, and in this instance it is good to see them getting it.
