And for some odd reason, there's a huge decline in the number of people who want to become policemen Down Under as well.

People who don't think this could happen here must think that America has more decent criminals than Australia. One of the reasons criminals don't break in to a house is that they think there might meet resistance. If they case a joint and see an old guy wandering around by himself they figure they can take him—unless there's a chance he has a gun. That chance will instill fear, uncertainty and doubt in the criminal, which is not just a sales tactic. FUD is a way to control behavior. It's a psychological fence, if you will, which you wield to get people to leave you alone. In many ways it's a first line of defense which might never be penetrated. Actually using a firearm might be a last-line of defense, but the right to bear arms is not, because of these many implications.

The criminal who would undertake a home invasion cares more dearly for his own life more than the law-abiding citizen, and he cares less about everyone else's life. He is a coward in the worst sense of the term. He preys on those he perceives to be weak and defenseless. A society which outlaws guns cares nothing about elderly people, single mothers, or poor people living in bad neighborhoods, no matter how big the social security payments or assistance checks are. In such an unarmed society, calling these people "at risk" because they have less money than suburbanites is a mean joke. These people are at risk because they can't defend themselves with aluminum ball bats or expensive monitored alarm systems. A fat lot of good government assistance will do for them when they're lying in a pool of blood because they didn't have a first or last line of defense against the criminal.
