Could a medical examiner's "interpretation" be biased? Certainly, though not very likely given the sheer number of people who will get a crack at it. Is the pastor's opinion biased against white people in favor of black people? Absolutely.
I'll believe any of these race mongers are genuine the minute they demand justice for children like Antonio Smith, Knijah Bibband, and McKenzie Elliot. Until that day, they can take their ridiculous pandering and shove it up their collective asses. I empathize with the lower income people who have to deal with both the scumbags in their neighborhoods and the police who are tired of dealing with the whole situation. It's a microcosm of the whole liberal ideal. Welcome to getting what you wish for.
