Bill Keller's interview with David Simon, creator of HBO's The Wire on The Marshall Project:
DS: Because the documented litany of police violence is now out in the open. There’s an actual theme here that’s being made evident by the digital revolution. It used to be our word against yours. It used to be said — correctly — that the patrolman on the beat on any American police force was the last perfect tyranny. Absent a herd of reliable witnesses, there were things he could do to deny you your freedom or kick your ass that were between him, you, and the street. The smartphone with its small, digital camera, is a revolution in civil liberties.
And if there’s still some residual code, if there’s still some attempt at precision in the street-level enforcement, then maybe you duck most of the outrage. Maybe you’re just cutting the procedural corners with the known players on your post – assuming you actually know the corner players, that you know your business as a street cop. But at some point, when there was no code, no precision, then they didn’t know. Why would they? In these drug-saturated neighborhoods, they weren’t policing their post anymore, they weren’t policing real estate that they were protecting from crime. They weren’t nurturing informants, or learning how to properly investigate anything. There’s a real skill set to good police work. But no, they were just dragging the sidewalks, hunting stats, and these inner-city neighborhoods — which were indeed drug-saturated because that's the only industry left — become just hunting grounds. They weren’t protecting anything. They weren’t serving anyone. They were collecting bodies, treating corner folk and citizens alike as an Israeli patrol would treat the West Bank, or as the Afrikaners would have treated Soweto back in the day. They’re an army of occupation. And once it’s that, then everybody’s the enemy. The police aren’t looking to make friends, or informants, or learning how to write clean warrants or how to testify in court without perjuring themselves unnecessarily. There's no incentive to get better as investigators, as cops. There’s no reason to solve crime. In the years they were behaving this way, locking up the entire world, the clearance rate for murder dove by 30 percent. The clearance rate for aggravated assault — every felony arrest rate – took a significant hit. Think about that. If crime is going down, and crime is going down, and if we have less murders than ever before and we have more homicide detectives assigned, and better evidentiary technologies to employ how is the clearance rate for homicide now 48 percent when it used to be 70 percent, or 75 percent?
