To understand what's happening in Baltimore, let's start from David Simon's interview with the Marshall Project. A former Baltimore reporter and the creator of "The Wire," he says that the police there long ago abdicated any claim to legitimate authority.

Police powers are inherently prone to abuse, but we grant them anyway, because the power is necessary to protect the community from crime. Simon argues that the Baltimore police stopped really pursuing that goal, so all that was left was the abuses. In a majority-black city with a black mayor, these dynamics do not neatly match our national assumptions about white oppressors and black oppressed. But they do back up the perception that the government cares only about the privileged, and will abuse you to benefit them.

Which is outrageous. You should be outraged. But you can be outraged, as I am, and still oppose the riots, as I do. The voices that try to rationalize the violence are presenting a dangerous false choice. They say that this was simply the inevitable result of monumental injustice, so let's stop talking about the riots and start talking about the injustice. We should always talk about injustice, and strive to end it. The mass incarceration state, the erosion of Fourth Amendment rights and the vast excesses of the drug war are perhaps the most important moral crisis facing our nation. But we have to talk about the riots too, because they represent another urgent moral crisis.
