Depends on your definition of the word "soon". Parts of Chicago are as safe as any city, anywhere, other parts are more dangerous than Zimbabwe. As long as Chicago has "cash cows" including O'Hare and the business district, I don't think it will become Detroit. (Or not exactly Detroit.)
"As part of David Bernstein and Noah Isacksons excellent piece on politicians and gangs in Chicago, we included a map of Chicago gang territory based on CPD information. Out of curiosity, I plotted 2011s homicides (through 12/11) and overlaid them on the gang-territory map. Its approximate, but its a useful rough sketch of the overlap."
Every time I see one of those maps of Chicago, I find the neighborhood where my dad grew up.
That area was heavily German and Polish, but it is now controlled by the Gangster Disciples, and he went to high school in an area controlled by the Black Disciples.
The Germans and Poles wisely moved out long ago.
