EDWARD CONLON: The Racial Reality of Policing: Police bias and misconduct are serious problems—but so is the epidemic of homicide among young black men.

It’s not up to me to decide what activists should protest, but after years of dealing with the realities of street violence, I don’t understand how a movement called “Black Lives Matter” can ignore the leading cause of death among young black men in the U.S., which is homicide by their peers.

In 2011, the Centers for Disease Control and Prevention counted 129 instances of black men killed by “legal intervention”—that is to say, by cops. The figure is incomplete because of a lack of national reporting requirements, and it says nothing about the circumstances of the killings or the race of the officers involved. But it gives a sense of the scope of the problem.

By contrast, in that same year, 6,739 black men were murdered, overwhelmingly by young men like themselves. Since 2001, even as rates of violent crime have dropped dramatically, more than 90,000 black men in the U.S. have been killed by other black men. With fatalities on this scale, the term epidemic is not a metaphor. Every year, the casualty count of black-on-black crime is twice that of the death toll of 9/11.

To talk about this vast slaughter isn’t changing the subject from police misconduct. It’s the only way a conversation about reforming police practices can begin.

In March, Attorney General Eric Holder released two reports on Ferguson. One covered in great detail the shooting death of Michael Brown by Officer Darren Wilson; the other described the broader patterns of policing in the city. Partisans have tended to choose one report or the other to support their reading of events.

No, Brown wasn’t shot in the back while attempting to surrender to a white cop, nor was he shot for jaywalking. He had just robbed a store, and he had punched Officer Wilson in the face and tried to steal his gun. In the wake of Brown’s death, Ferguson burned because people believed a lie; because many still believe it, cops have been shot there, and the threat of riot remains.

The other report showed that Ferguson was a speed trap for people going nowhere, six square miles of mostly black people, mostly poor, with 50 cops, almost all white, who were ordered to milk them for every possible nickel by white city managers. Black people were further bled dry in a punitive cycle of fines and fees; missed court dates led to arrest warrants, which left them increasingly incapable of having a chance at a productive life.

Which story to emphasize? It depends on your agenda.

Indeed it does.
