You need to read the article for full effect. It reads like a parody of gun-control advocates criticizing gun availability.
I wonder how many deaths cigarettes cause per year in Australia.
This article is actually thanks to me. Several years ago I posted a gun-control parody about swimming pools on a Swedish board. Some months later there was an article in a Swedish newspaper - obviously missing the irony in my post - about how dangerous swimming pools were. Now it seems that it has reached all the way to Australia, where people thankfully understood the irony and the absurdity of gun-control.
By the way: more people are actually drowned in swimming pools than killed by guns - even in America. Yet I have never heard any serious suggestion about banning or even restricting swimming pools.
The cigarette argument is also good: in Sweden less than 80 people a year are killed by guns, while more than 8000 are killed by smoking. Yet it is tobacco that only has an age limit of 18 years and guns that are controlled draconically.
