In March, something happened in Kentucky that tragically seems, in light of what happened to Alton Sterling and Philando Castile last week, business as usual. Constable Bobby Smith wanted to serve a warrant to Brandon Stanley, who tried to evade him. Smith tracked Stanley down to a convenience store and shot him dead.
Around the same time in Arizona, Daniel Shaver was playfully waving a pellet gun out of a motel window. A police officer detained him, and despite Shaver complying with all of his demands (there is a video) shot him dead. Also around this time in North Dakota, James Scott, allegedly intoxicated, dropped a gun and fled police officers but refused to put his hands up when detained; they shot him dead.
The men in these cases were white, not black, and yet all three were killed by police officers under circumstances that would almost surely have elicited indignant protest nationwide if they were black.
Cases of this kind are dismayingly numerous.
