And the third source does...but to be fair I never counted that source as being entirely credible. I'd have to research it before I said that.
Regarding assaults in Australia:
http://www.gunsandcrime.org/auresult.html
It is true, as claimed by gun possession advocates, that the assault rate has increased a lot since the ban/buyback. But the ban/buyback cannot be blamed for this since the rate was increasing at essentially the same rate before the ban/buyback (and the other changes) began. The rate did not rise as fast for '99 and 2000, but then rose even faster than before for '01 and '02. The ban/buyback did not have a definite effect of any kind on the assault rate—neither improving it nor making it worse. It is possible that the small declines for '99 and 2000 were caused by the ban/buyback and other changes made at the same time. But, if so, something must have completely counteracted that in '01 and '02.
But like I said...that's not my argument. That's an argument you're attempting to force me to make.
