Curious Mind, I too have a rather “curious mind” as to why the difference between here (Australia) and the USA. I live in what might be termed a “disadvantaged” neighbourhood:
i.e. A low socio-economic area, with a significant “indigenous” population and a large number of immigrants (a real “spot the Aussie” type suburb).
Despite all this, there are few serious law and order issues - and without the population being armed to the teeth.
By contrast, we are being told on this forum that in the USA, one is not safe unless fully equipped with an AR15, 30 round magazines and (presumably) enough ammunition to fight a small war. How that situation came about would make interesting reading!
