There are small counties and county jails where 80-90% of the violent and property crime have been done by literally the same 3 or 4 people.
As in, the county records thousands of crimes and a single perpetrator in the gang has done as many as 400-500+ of them in the span of a few years.
People always mistake a crime committed for a person committing a crime. In reality it's a very small bunch of psychopaths committing a huge amount of crime with no regard to punishment or consequences (or the people they hurt) until they finally get caught.
Outside the US, the numbers are even more extreme in some countries like Sweden:
>The 1 % of the population accountable for 63 % of all violent crime convictions
Nearly 2/3rds of all violent crime was done by a tiny portion of sociopaths - robberies by ethnic swedes, assaults and rapes by foreigners.
But it's not a huge number of people committing these crimes. We're talking about around 50-100 people committing thousands upon thousands of crimes repeatedly, sometimes for years before getting caught.
