Last week, a gunman entered Marjory Stoneman Douglas High school in Parkland, Florida and killed 17 people. Yesterday, Emma Gonzalez, a senior at the school, delivered a powerful, rousing speech about gun control at a rally. Today, the students of Marjory Stoneman Douglas announced March For Our Lives, a March 24 march on Washington, DC for gun control. March For Our Lives website reads, "Every kid in this country now goes to school wondering if this day might be their last. We live in fear."
