Yes, definitely Australia, and formerly UK.

Neither has what I call, a "gun culture" and neither has a violent society. I admit these are not hard-linked, but perhaps a soft-link? The "inalienable right" to form a militia, defend oneself, and bear arms? - doesn't lead to peaceful resolution of domestic violence!

(Unfair point. Even in America, only a fraction of husbands abuse their wives. The task is to reduce the fraction, and cut down on mutual aggression.

It isn't just population density. The UK is more crowded, on average, than the USA buit has ~1/10 the violent crime. Australia is 1/100 or 1/1000 the density, and has crime rates similar to UK.

In the USA, there are no simple State-based relations to crime. (vs population, urbanisation, economic success etc.). There *is* a hint of a link to %(non-white Americans), but there are so many social factors embedded here it isn't worth touching...

I respect your views, but differ.
