Reply to comment by carpeson in Examining 100,000 crime-related posts from 14,000 Facebook pages maintained by U.S. law enforcement agencies between 2010 and 2019, researchers found that Facebook users are exposed to posts that overrepresent Black suspects by 25% relative to local arrest rates by giuliomagnifico

Yes; you continue claiming i didn't understand your point that police presence mediates a lower actual - documented crime gap in low income urban settings, but this is unlikely. Homicide rates are measurement invariant, and because there's a positive manifold for criminality, you should be able to extract theoretical actual crimes rates from homicide rates plus a few other hopefully somewhat orthogonal (and measurement invariant such as reported stolen vehicles to insurance companies or law enforcement?) input variables. The gap between theoretical crime - documented crime would give you the evidence for which regions have the highest crime gaps, and whether crime gap variance is associated with law enforcement presence variance to establish an unlikely hypothesis.

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.
