Viral Swing: March for our Lives: Parkland student Emma Gonzalez ends Washington rally by telling crowd to 'fight for your lives'

Thirty-eight days after the massacre at Marjory Stoneman Douglas High School, hundreds of thousands of students across the country have taken to to the streets in an anti-gun violence protest of unprecedented size. The marches – which consists of a main event in Washington DC alongside sister protests in New York, Los Angeles and hundreds of communities across the country and around the world – is the culmination of weeks of planning by student survivors of the Parkland, Florida shooting in which 17 people were killed on Valentine's Day. The focal point was the March for Our Lives rally in Washington DC, but tens of thousands also turned out in New York, Boston, Los Angeles, Chicago, Houston and Minneapolis in demonstrations sparked by the survivors of the mass shooting at Marjory Stoneman Douglas High School in Parkland, Florida on Valentine’s Day.
