This is why Trump, US Congress, or anyone else outside of Chicago or IL offering "help" is useless, and a political trap. The Governor of IL can call out his national guard - he does not. Rahm Emmanuel and the cops can call a state of emergency, cancel vacations for police, etc... but they do not. They really don't do anything.
They will do nothing, and the locals will continue the same cliches, voting patterns and behavior. As such, anyone outside of Chicago should simply leave it alone.
It is irreversible.
Worse, it will continue inexorably into chaos.
No law enforcement type solution can have any serious positive effect after 50+ years of social decay. Accept that Chicago is lost for good.
Sadly, I concur.
