I've lived a half hour outside of Detroit my whole life and what you just said is a huge broadbrush!
Lived in Rochester Hills, and worked in both New Center, as well as downtown for three years........during that time, I personally had 16 vehicles vandalized, two stolen outright, my wife a victim of an attempted assult, and my best friend, who lived in a townhouse a few blocks west of New Center, murdered in his bed, and his wife beaten and raped.......
Another friend, an attorney for a law firm in the RenCen, was carjacked and beaten so badly coming out of his parking deck that he is in a wheelchair yet today, with little possibility of recovery.......
Oh, and by the way.......none of the aforementioned crimes have ever been solved........
Please don't lecture me on conditions in the lovely City of Detroit.......
BTW......I also lived there in the mid-sixties, when it was really a nice place to be.....spent many a Saturday night dragging Woodward Ave.....fond memories, but alas, no more........
