Cops should leave that city. Why are they there? Let the fine citizens live in the kind of community they want and build.
Where do you get the idea that everyone in Ferguson supports crime, rioting, looting, and nightly protesting? The protesters and rioters seem to be a relative handful, a small minority of the AA minority — maybe 200 individuals acting at different times, out of a population of 40,000. 80%+ of the residents have no sympathy for this circus and need to be protected from the feral element that moved into their city via federal spending. Without Section 8 housing projects this would be a normal middle class community.
