SPRINGFIELD, Mass. (AP) — Student gun control advocates and one of the survivors of the Parkland, Florida, school shooting are finishing a 50-mile, four-day march in Massachusetts to the headquarters of gun manufacturer Smith & Wesson. The group is gathering outside company headquarters Sunday in Springfield. The marchers have 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. The Boston Globe reported David Hogg, a Parkland shooting survivor, called the march empowering and said Massachusetts shows how commonsense gun laws work. Another group held signs across the street from Smith & Wesson supporting the gun-maker and the Second Amendment. Smith & Wesson hasn’t responded to requests for comment.
