A good long piece by Mother Jones on
patterns of police violence against unarmed black Americans:
In 2007, ColorLines and the Chicago Reporter investigated fatal police shootings in 10 major cities, and found that there were a disproportionately high number of African Americans among police shooting victims in every one, particularly in New York, San Diego, and Las Vegas.
"We need not look for individual racists to say that we have a culture of policing that is really rubbing salt into longstanding racial wounds," NAACP president Cornell Williams Brooks told Mother Jones. It's a culture in which people suspected of minor crimes are met with "overwhelmingly major, often lethal, use of force," he says.
In Oakland, California, the NAACP reported that out of 45 officer-involved shootings in the city between 2004 and 2008, 37 of those shot were black. None were white. One-third of the shootings resulted in fatalities.
Pairing the militarization of the police force—not just in spare military weaponry, but in military-inspired tactics—with the historic aggression of many American law enforcement offices against minority suspects has had predictable effects over and over. We built this.
