Today marked a nationwide school walkout, in which students across the country demonstrated to mark the one month anniversary of the Parkland, Florida shooting that killed 17 people. Here in Massachusetts, many students were not in school because of the snow day, but they gathered at the State House regardless to let their voices be heard. Jim Braude was joined by two of the student organizers — Eloise Botka, a junior at Cambridge Rindge and Latin School and Laura Luiza Cabral Gouveia, a sophomore at Somerville High.
