Wall off the city and let the Africans live as Africans want to livePoint of information. Chicago is not majority African Americans. They are not even the second most numerous group.
Also worth noting: The "teens" behave like this in their own neighborhoods, and now also downtown. But not in Mexican neighborhoods, not in Chinatown, not in the remaining White Ethnic enclaves.
Among the hundreds of videos I have seen I have only seen one instance of “teens” of the latino persuasion ransack a store in Los Angeles. I feel safe in assuming the “teens” are of the melanated time terrorizing Chicago’s green zone.
