The DoJ confirmed that the Brown shooting was justified, yes. The Zimmerman case, my issues were always that the only reason that situation became violent was that Zimmerman was stalking him to begin with; he should have faced some consequences for instigating that, even if the actual shooting was deemed justified.
I'm not being inconsistent, and my positions on these things have never been determined by race. I'm not the one desperate to bring race into this, every time. You folks are the ones dragging it up, here, when it has exactly zero relevance.
