People gathered in cities across America on Saturday for massive student-led protests to demand stronger gun control measures. Hundreds of thousands took part in large “March for Our Lives” protests. They took place in major cities including Boston, New York, Washington D.C., Los Angeles, Chicago and Parkland, Florida. Parkland was the site of the February 14 attack at Marjory Stoneman Douglas High School that left 17 people dead. Some international cities also held demonstrations. The protests were organized by students after the Parkland shooting. One of the largest took place in Washington D.C. Several survivors of the Stoneman Douglas tragedy spoke to the crowd from a stage set up on Pennsylvania Avenue. Among the survivors to speak was 18-year-old Emma Gonzalez, one of the leaders of the student-led gun control movement. She began by saying it took the gunman in the Parkland shooting only a little over six minutes to kill 17 people, and injure 15 others.
