Again, you can't take a law and simply transplant it somewhere else and expect the equivalent outcomes.
Has Australia had a revolutionary war? An armed civil war? Are Australians constitutionally granted the right to bear arms? How many guns were owned before and after the controls?Exactly. Also, not all gun deaths are the same. For example, concerning this stat, stated earlier:
"Of all the 5 to 14 year olds shot in the developed world, 90% of them were Americans"
And of that 90%, what percentage of those deaths are inner city gang violence, primarily with hand guns? Every day, literally each day that goes by, more people are killed in Chicago alone. The gun control measures there just disarm the law-abiding.
