I don't think that in Australia we have anything like a militia. We have a standing army of professional soldiers and weekend reservists. After that we have professional police forces at state and federal levels.
In my mind militias are a worry. We have seen militias in operation in East Timor where they terrorised the local population on behalf of the Indonesians and the insurgents in the Middle East are referred to as militias. They have some internal organisation and ISIS does seem to be well co-ordinated but well regulated? By whom?
I can understand the National Guard being an acceptable militia according to the American Constitution but can any one point to another organisation that could be termed a "well regulated militia" ? That is not a rhetorical question. I really want to know.
When our constitution was written and the Second Amendment was added, there was no such thing as a National Guard. This is not a militia. It is just another part of the regular military, and they are sent overseas just like any other part of the miliary here.
The original wording plainly said that every person had the right to self-defence, but that these people would also be called upon in times of need as a militia. They had to have their own weapons, horse, knapsack, ammunition, and anything else needed for the defense of the country.
If you think about it like a house catching on fire, and the fire spreads. The fire engine comes, but if the fire keeps on spreading, then every person that can help stop the fire is going to help. They are not truly firemen, just people protecting their homes, and their neighbor's homes.
The militia is basically the same thing. The original wording specifically says that every person has the right to own weapons, and that this right shall not be taken away from him.
It has nothing to do with being a sportsman or hunting, and everything to do with self-defense.
Suppose America were attacked by China, Russia, or some other country. We would then have every person that owned any kind of a weapon out there fighting for our freedom, and that would be our militia. The same thing would hold true if Australia were attacked, and needed every available person to help defend the country.
