I love this quote, in particular: 

"On the other hand, in families and churches and workplaces, there’s a possibility that people are a little bit more honest, and at least you ask yourself your own questions about, am I wringing as much bias out of myself as I can; am I judging people, as much as I can, based on not the color of their skin but the content of their character? That would, I think, be an appropriate exercise in the wake of this tragedy."  -- President Obama
