The photos of protests around the country following the death of George Floyd during an encounter with Minneapolis police are hauntingly familiar. We’ve seen them many times before, going back decades.Why it matters: "What is also unmistakable in the bitter protests in Minneapolis and around the country is the sense that the state is either complicit or incapable of effecting substantive change," Keeanga-Yamahtta Taylor, an assistant professor of African-American studies at Princeton University writes in the New York Times. The images that follow make all too clear how little has changed since the modern Civil Rights Movement began in the 1950s. Now: Baltimore police arrested Freddie Gray, 25, on April 25, 2015, and charged him with carrying a knife. While in police custody, he fell into a coma and died a few days later. Protests started and quickly escalated after police failed to release information regarding Gray's injuries. The police officers charged with his death were either acquitted or their cases ended in mistrials.

As long as the hope was fulfilled there was little questioning of nonviolence. But when the hopes were blasted, when people came to see that in spite of progress their conditions were still insufferable … despair began to set in...Darkness cannot drive out darkness: only light can do that. Hate cannot drive out hate: only love can do that. The beauty of nonviolence is that in its own way and in its own time it seeks to break the chain reaction of evil,” Martin Luther King, Jr., wrote in his 1967 book, Where Do We Go from Here: Chaos or Community.
