Wow, lots of people are taking about the great gun control they have in Australia in the wake of the Charleston shooting. Most noteably even the President mentioned it. Zero shootings since 1996 they claim. I know very little about AUS so I looked into the country briefly. I like to start with demographics. After all, to make such bold statements like we should adopt their gun control model we must be very similar, right?

Land mass:
Australia 2.97 million miles
U.S. 3.8 million miles

Population
Australia 23.13 million
U.S. 318.9 million (population of CA alone is 38 million)

Largest city
Sydney 4.3 million
NYC 8.4 million

Almost 50% of its ENTIRE population is within the largest 3 cities!
It jumps to 60% if you count the largest 5 cities.

The largest 5 cities in the U.S. combined make about 19 million people about 6% of the total population.

Keep in mind that the U.S. and Australia are very similar in physical size. Maybe not a 1-on-1 good comparison?

See something about the demographics that might make AUS a little different than the U.S.? By the way, all these numbers come from internet Google and Wikipedia.

And speaking of Wikipedia...so there is the assertion that gun crime/mass shootings stopped in 1996 after the Port Author Massacre.
According to Wikipedia that is not true. There are at least two: https://en.wikipedia.org/wiki/List_of_massacres_in_Australia

That's as far as I have got so far. I stopped reading at the point that their constitution had "implied rights" and that voting was one.

Anyway, just some thoughts...
