It was literal nigger behavior, and it only stopped because actual niggers pushed them out of the cities and voted themselves into all the city governments.
Retard, niggers don’t organize anything. Nigger run cities are because some stupid Whites had to sell flagellate and act like monkeys can run human cities.
The Irish Mob stopped being concerned about petty street crime because they ran NYC and Chicago and many other places besides. Al Capone cut his teeth under an Irish Mob boss. The Irish by the 1960s could put Kennedy in office. Italians simply followed their playbook - which, as it tirns out, means going legit as soon as possible. No one drives off of a construction site every worker calls him Boss at, to break kneecaps over petty debts in a back alley.
Niggers have never figured this out. Instead of a means to an end in a country vaguely hostile to their presence, niggers see it as the Way To Be in all circumstances - which is why Mansa Musa was pawning off items left and right on his return from Mecca. Nigger rich is forever.
Niggers and beaners entered into a vacuum created by the Micks and Dagos leaving the streets to whoever gave a fuck about them, just like we left boxing to the subhumans because there’s better ways to earn a living now.
As always, Anglos stay malding about the black eyes the Irish gave them, because while every other country freed by them besides the United States simply got let go because the Empire was too weak to hold those lands anymore. Similarly, while Anglos simply abandoned Detroit, Flint, Baltimore etc to niggers out of a lack of will, they still cry about the fact that the Irish didn’t ask for Boston or NYC - they took them.
