Great input. I still don't believe that's the whole picture. In most of Europe less weapons have a strong positive correlation with less homicides so we can't use this metric to encompass most of the crime spectrum. Car theft is much more common and can definitely be used as another way to approximate g. This still doesn't include drug trade and prostitution. Most of the times such cases of organized crime have their own Para-justice systems in place where allowing one crime doesn't automatically mean you allowed every crime (most notably homicides, which are a big no-go even in communities where crime is normalized).

I also believe we are working with a moderating force, not a mediating one but that's besides the point and might be quite a high-level criticism.

There is still much to be discovered in this field. Looking forward to some new discoveries.
