Sane people moved out of Detroit proper a long time ago.
A high school friend of mine had an older brother and his older brother got in a car wreck down in DC. Two guys got out of the car and beat him so badly that he has never been the same mentally ever since, and I don’t mean a Psychotic Reaction, he is severly mentally impaired because of the beating he took at the hands of those two. They were never caught. This was in the 70s.
