BOSTON/North End - On Saturday, 30 people marched from Copley Square to the Paul Revere Mall in the North End to commemorate the 81st anniversary of the execution of Italian-American anarchist organizers Nicola Sacco and Bartolomeo Vanzetti. Rallies at both ends of the march celebrated their lives, and mourned their deaths. The event was organized by the Boston-based Sacco and Vanzetti Appreciation Society.
