Yes, protests often are used as an excuse for some to take advantage, just as when fans celebrating a hometown sports team championship burn cars and destroy storefronts. I don’t want to see stores looted or even buildings burn. But African Americans have been living in a burning building for many years, choking on the smoke as the flames burn closer and closer. Racism in America is like dust in the air. It seems invisible — even if you’re choking on it — until you let the sun in. Then you see it’s everywhere. As long as we keep shining that light, we have a chance of cleaning it wherever it lands. But we have to stay vigilant, because it’s always still in the air.
