Too bad no one in Australia has a firearm with which to protect themselves...(*ssh*les)...
Ah - we do.
I've been carrying to and from work since the London bombings.
The effect of Australia's gun laws have been greatly exagerated - there are some restrictions, but there are still millions of legally held firearms in private hands in Australia, and virtually any adult without a criminal record can get a firearm permit if they want to. Handgun permits and permits for semi-automatics and automatics are harder to get, but it can be done.
Careful That's America's best friend you're talking about.
