This happened on Christmas Day in Australia.
This incident was the result of thefts from patrons of a Vietnamese business, but this type of situation is not new and the Vietnamese community is sick of it.
Conflict between African and Asian groups is not uncommon for various reasons but we saw similar friction in the US and UK.
The difference here is that the lack of gun rights and self defense rights have put the Vietnamese community at the mercy of the Sudanese.
In the US, the Korean shop keepers were able to defend themselves.
Gun rights are minority rights because it allows minorities to protect themselves when no one else will.
