fwiw...
this page has quite a few pertinent facts. Whether they're reliable or not I don't know but assuming they are reliable....
I looked at assaults per capita, murders per capita, and murders with guns per capita across the spectrum, then narrowed things down to US, UK, Canada, New Zealand and Australia because the data was available for these countries (not for india and france) and all five have assaults per 1000 in the 7-8 range.
so...
country, assaults per 1000, murder per 1000, murder by gun per 1000, guns per 100 residents
US 7.6 0.043 0.028 90
UK 7.5 0.014 0.001 ~5
Aus 7.0 0.015 0.003 31
Can 7.1 0.015 0.005 32
NZ 7.5 0.011 0.002 26
The glaringly obvious conclusion is that the difference in murder rates in the US versus the other five countries stems from gun fire -- basically...if 28 person per million are murder from guns during the year in the us and if the us has about 26-30 more murders per million per year then it doesn't take a brain seargant to figure out the problem, right? Thus, by taking guns out of the mix you reduce the murder rate to 15 per million, or 0.015 per thousand in which case the murder rate in the US is comparable to UK, Aus, Can, and NZ....Right?
If we reduce the number of guns down to the number in Can, Aus or NZ, we ought to expect comparable gun related murder rates and we can expect stats to look something like this:
country, assaults per 1000, murder per 1000, murder by gun per 1000, guns per 100 residents
US 7.6
0.019 0.003 30
UK 7.5 0.014 0.001 ~5
Aus 7.0 0.015 0.003 31
Can 7.1 0.015 0.005 32
NZ 7.5 0.011 0.002 26
Right?
