Seems to me that the Italians are doing better here.
You basically see the homicide rate spike up in conjunction with mafia wars, which can kill up to 1000 victims in the span of a handful of years.
It's almost like there are different factors that affect crime rates than simple access to firearms :^)
Would that be considered one of your 'different factors', that it has no real urban environments to compare to New York (eg NYC 8M) or Italy (eg Rome 4M)? Hardly an apples-to-apples comparison.
Let's try Washington, D.C. (population ~600,000) with almost 22 murders per 100k vs Houston, TX (population ~2 million) which had 11.8 murders per 100,000. Both are urban environments, and in this case the more populous one did not have a higher homicide rate.
But let's back up for a second and see if these differences are even meaningful. Comparing the overall rates for the US and and Italy (and assuming that all people are equally likely to be murdered), you have a 0.00001% chance of getting murdered in Italy and a 0.00005% chance of getting murdered in the US.
you have a 0.00001% chance of getting murdered in Italy and a 0.00005% chance of getting murdered in the US.
Presenting the statistics this way? Yes, you really do need to study criminology a bit more to understand why this is a bad way to present data. In Honduras, you have a 0.0009% chances of getting murdered (per year). Still sounds tiny, yet that country is the murder capital of the world and very much not safe to live in.
It's also worth noting that I never said that crime was directly proportional to population.
Edit: the other side of the 0.00005% argument is: if you're making the argument that it's really rare to die from guns, then why bother with the 'if only X had a gun' argument? If it's that 'rare', why bother making that argument in the first place?
