The truth about gun ownership after Port Arthur - The Drum (Australian Broadcasting Corporation)
One thing that interested me in this is the explanation that the increase in gun numbers in Australia in the last decade or so has not been into more households - proportionally, about the same number of households have guns. As the author notes, this is a similar phenomena as has occurred in America.
In America, I take it as pretty convincing evidence of the paranoid streak that runs in its right wing politics (especially in the last decade or two), and reading the gun nutters who comment at Catallaxy, I find it hard to deny there is a similar strain in Australia.
Those in Australia who buy one (or want to buy one) for self protection ignore the risk to themselves and their family that having a gun in the household creates. (Nor the fact that there's a good chance the crim's gun they are worried about had a good chance of having originally come from a legal owner.) But then again, scratch a gun obsessed nut, and you'll have a much better than even chance of finding a climate change denier, too. They just aren't good at understanding the big picture.
