Article argues that inner cities get too much drug enforcement policing and not nearly enough violent crime policing -- clearance rate for violent crimes there being much lower than in white suburbs. Makes brief analogy to the "boots on the ground" and surge policies in Iraq; brings up lack of local control of police and prosecutors.

Comments bring up other factors, like "no snitch" culture in the neighborhoods; cause and effect between police ineffectiveness and local distrust of police might be entangled.
