In a sense it is going on in Detroit but its not organized. The elderly are taking a hell of a toll on the thug population.
The justifiable homicide rate in Detroit is an astounding 2200% higher than the national average. Part of the problem is the manipulation of statistics. The government loves to count those justifiable homicides (defensive) as murder without a distinction. Just guessing from watching the news I’d say its about 5 defensive shootings per week in Detroit.
