As I looked at the demoralized faces in the room, I understood why the week left us all so drained and depressed. For decades people of color have protested against discriminatory and violent policing. And while there have been some meaningful victories over the years, we have yet to win the true accountability that we need to secure our full civil rights and dignity. Ever since the death of Garner in my city — in some ways ever since the beating of Rodney King in Los Angeles 25 years ago — we’ve had the proof right in front of us, on our screens. We thought this new phenomenon — ubiquitous cameras providing new evidence of an enduring injustice — would shock the nation into action, but it hasn’t. We have organized and marched and rallied, thinking it would move the nation to value our lives and reform its policing. But it hasn’t.
