"It's been six years, and you've done nothing," Joaquin Oliver's voice echoed across the U.S. Capitol grounds Wednesday. "Not a thing to stop all the shootings that have continued to happen since."
On Feb. 14, 2018, Oliver started another day as a senior at Marjory Stoneman Douglas High School in Parkland, Fla. By the end, he was one of 17 people murdered at the school in a mass shooting that sparked a worldwide, youth-led movement on gun violence.
