There are such imagined grudges that when something that really does bear investigation takes place, all ugliness bursts forth.
Let all applicable investigation happen in the case of Grey, and no I don’t buy implications that somehow he ought to have been killed because he has committed (or been arrested for) a lot of drug crimes. But neither should we have the Evil Auntie in DC screeching prejudicially that this is the result of some evil white plot.
You’re right. Rational people of all races do NOT want police being judge, jury and executioner. We have to walk everyone away from that madness...
