I lived the same story. We moved my grandmother out after a mugging. Do you remember Coleman Young? He was the mayor that won election campaigning against STRESS. He really was a racist.
Yeah, on the day he was elected Coleman Young told criminals "to hit 8 mile rd". He was announcing he wasn't going to work with the white suburbs, he was going to drive Detroit's problems into them. And that's about what happened.
He was a terrible mayor. But in truth, so was Jerry Cananaugh and the white guy that followed him.
The problem with so many of America's big cities is that THERE IS NO P0LITICAL COMPETITION as long as one party as complete control nothing is going to change.
