On March 14, 2018, students walked out of their classes to protest against gun violence in a demonstration across the country. The call for the walkout emerged in response to last month's shooting at Florida's Marjory Stoneman Douglas High School, when a lone gunman opened fire, killing 17 people. Students rally outside the Capitol Building in Washington on March 14, 2018.
