More than 100 protesters rallied outside company headquarters Sunday in Springfield. The marchers condemned Smith & Wesson for making the rifle used in the February mass shooting at Marjory Stoneman Douglas High School in Parkland. The group wants the company to donate $5 million to gun violence research. Parkland shooting survivor David Hogg called the march empowering and said Massachusetts shows how commonsense gun laws work. Counter-protesters held signs across the street from Smith & Wesson supporting the gun-maker and the Second Amendment. Police kept the two protests separate. Participants began their march Thursday, setting off from downtown Worcester, holding signs denouncing gun violence and chanting slogans criticizing gun makers and the National Rifle Association. Smith & Wesson hasn’t responded to requests for comment.
