There being a current shortage of dead alleged entertainers, our managers seem to think we Americans need some other diversion to prevent our noticing the ongoing government/corporate looting of the wreckage of the republic. So, this non-story has legs that keep on runnin'.
The professionally-racially-aggrieved appear to be willing to be mollified, if only the cops could show that they abuse white people at the same rate as colored people. And most white people appear to think that it's fine that the cops should go on abusing people, because they're pretty sure that white people aren't getting cop-abused.
It's the old divide-and-dominate game. Get us at each other's throats, and we won't ask why we should pay a whole class of uniformed thugs to abuse us. We'll just quibble about the details of the distribution of the abuse.
Want less cop abuse? Have fewer cops -- lots fewer cops.
