Problem in Detroit is that the Police Dept is a joke, corruption is at the higher levels and there is not real leadership for those who truely want to help out the city. From the circus called City Council down to the upper echelon of the PD, there is few, if any, true leaders, most are political posers.
Other problem is, if all the store owners in the D close down and move out, two things happen. The people left behind who can't move out suffer with nowhere to shop. The second problem is the punks have to come out to the suburbs to do their crimes. Better they stay below 8 Mile.
