No, Australia is not the US. Our shocking racial injustice is all our own -
African Americans make up 12% of the adult population, but 33% of the US prison population; in Australia the ratio for Indigenous people is 3% of the population and 29% of the prisoners ... Indigenous women account for 36% of all women behind bars.
If we could just replicate the ratio of African Americans in prison for Indigenous people, total prison numbers in Australia would fall by around 22%
When things would so greatly improve by only being as bad as the US, you know things are in a woeful state.
If the rate of Indigenous men in prison was the same as that of non-Indigenous men, rather than having 11,682 Indigenous men in prison there would be just 760 – cutting the total male prison population by more than a third.

we've had over 400 deaths in custody since a Review/Royal Commission in 1991 & no-one has ever been charged.
