Mayor Stephanie Rawlings-Blake, the governor, members of the state's congressional delegation and other leaders are urging calm, as are many of the city's religious leaders. It will take more than that. It will take the thousands who have already marched in peaceful solidarity with the Gray family's cause, and the many thousands more who have silently supported them, to take back the movement, to drown out those few who choose chaos over order. The Gray family's attorney, Billy Murphy, suggested on CNN that the Freddie Gray protests pause until the city comes under control. That's an understandable sentiment, but if we are to not only restore the peace but also realize something positive from the memory of Freddie Gray, it will take more than silence. All the rest of us must speak out and do our parts to find solutions to the injustices that pervade the inner city where he lived and died.
