I'll give you some background information as an Australian living in a city very close to a dry community.

The Government has ruled that many aboriginal communities are to be "dry communities", which is to say the sale and I believe possession of alcohol are banned. The idea, of course, is protection of our precious minorities. Previously, the aboriginals would happily sit in their communities, beat and molest their own children and generally commit all types of heinous crime on one another. The implementation of the dry community mandate meant that the alcoholic aboriginals who used to commit those crimes to afford their swill and sate their lizard-brained urges now had to enter polite society to get their next fix.

This ended just about how you would expect; they litter the parks and the alleys drinking themselves blind in the day-time, and form roving bands of danger at night in order to fuel their habits. Some of them take to sniffing (and reportedly drinking) petrol. It is a whole thing.

Dumbass academic types, like these authors, tend to follow in lockstep with the opinions of the south-east (Sydney, Melbourne, Canberra, etc), and it just so happens there are very few aboriginals in the south-eastern states. The few that do live there appear to live in a perpetual state of grifting, pushing for land to be considered "sacred" to whatever aboriginal tribe they hold allegiance to and litigating anyone who so much as looks at it askance. This results in basically no-one there really knowing how dangerous it is to go outside at night anywhere with a sizable aboriginal population without being in a large group. Interestingly, these two idiots apparently actually live in Alice Springs, but I'm sure we've all seen the tendency of the overeducated to disregard information they can gather by simply paying attention to their own surroundings.

To address the question finally, that is certainly a problem, but that's more a south-eastern state thing. Here I would hesitate to say the protected minority is doing "nothing". They actively terrorise the communities that they squat in to chase their next high, and the cucked white people are trying to enact a pathetic kind of prohibition only in aboriginal communities, without realising that, oh right, prohibition didn't fucking work for a reason.

Anyway, thank you for coming to my TED talk.
