The crime is mostly limited to isolated spots around the south and west sides and it's not just black people shooting, a lot of it is Mexicans too.
Plus, think about it like this, if 8 months out the year absolutely nothing happens cause nikkaz can't go outside (wintertime), then having all of your crime concentrated into 4 months might look bad...but it really works out to be, over the span of a year, the same amount of crime that would go down in Atlanta or Houston or NO or Raleigh or LA where nikkaz are out year round.
Chicago is a beautiful city
