Second, I’ve heard some suggest that the recurrent problem of racial bias in our criminal justice system proves that only protests and direct action can bring about change, and that voting and participation in electoral politics is a waste of time. I couldn’t disagree more. The point of protest is to raise public awareness, to put a spotlight on injustice, and to make the powers that be uncomfortable; in fact, throughout American history, it’s often only been in response to protests and civil disobedience that the political system has even paid attention to marginalized communities. But eventually, aspirations have to be translated into specific laws and institutional practices — and in a democracy, that only happens when we elect government officials who are responsive to our demands.
