Had a coworker from a former life in Indonesia. He told me that the cops in most of the cities kept files to clearly identify the 1-2% of the population which accounted for 98-99% of the crime. On a slow night, the local precinct would decide which ones should die in a street brawl or some other kind of accident. There would always be an investigation, but the crime would not be solved.
Not saying we have cops who do that in America but at one time we had vigilantes, sometimes under the cover of organized crime, who performed the same function.
Only problem - that’s not justice.
