“Like many other academics studying protests and movements, I am often asked if protests work—an especially important question for the ongoing Black Lives Matter protests as they, like all crowded events, entail extra risk during a pandemic. Will all this accomplish something? The answer is, yes, of course protests work, but usually not in the way and timeframe that many people think. Protests sometimes look like failures in the short term, but much of the power of protests is in their long-term effects, on both the protesters themselves and the rest of society.”
