Bostonians march toward the Common against racial hatred and President Trump and a group of "Free Speech" demonstrators who they consider Nazis.A man wearing a Trump shirt reportedly harassed the Black Lives Matter demonstrators and police took him into custody, but he had angered the crowd and they pursued him and the police up Beacon Street throwing water at him and police to the State House where the man was held. A show of force by police and special operations units and pleas from Black Lives leaders caused the crowd to back away.
