I know what we can do about it, but it would involve a lot of white people. I would start with proper gun control restrictions in the area while declaring a state of emergency in the city. From there, proper staffing and training of the police department followed by education for the masses, the problem would be fixed in about a generation.
The problem with my solution? Getting a bankrupt Windy City in a state that hasn't had a budget for close to 3 years (thanks republicans) to agree on anything when it comes to people of color.
