Evangelion, you said, “The very fact that Australia (along with every other nation in the developed West) has never found any need for such a policy, should tell you that we are getting it right where you are getting it wrong. ”
My aunt and uncle are currently visiting Australia and sent an email about a memorial they visited in Port Arthur. They said they visited a site where a gunman killed 35 people in 1996. A rare incident in your country, but we see that it can happen almost anywhere.
Don’t misunderstand me, I realize that Australia has an incredibly low homicide rate (somewhere around 2.1 per 100,000 compared with the current US rate of 5.5 per 100,000.) They point is, “monsters” can be created almost anywhere. It could be that Australia, with its small population of only 18.5 million (in 2000) just hasn’t “caught up” demographically with the US and its population of 287 million (POPClock).
