. . . To put in another way: Austrialia has a much lower murder rate then we do. Perhaps we should implement their gun control policies?
Australia in general has a very different demographic than Chicago does.
Some time ago, Chicago did a study of murders over a 20 year period. At the time, about 3/4 of murders were committed by persons with prior criminal records. The bit of good news was that around 2/3 of the victims
also had criminal records, putting most of the killings into the "good riddance" category.
The big problem is the study also included demographic data which showed that the vast majority of killings were committed by certain ethnicities . . . and
that statistic was politically unpalatable, so the results of the study were studiously ignored.
