15 photos of March for Our Lives in D.C., Texas, London and Parkland

“Six minutes and 20 seconds. In a little over six minutes, 17 of our friends were taken from us, 15 were injured and everyone—absolutely everyone—in the Douglas community was forever altered.”

Marjory Stoneman Douglas senior Emma Gonzalez took the stage at the March for Our Lives in Washington, D.C. on March 24, and listed the 17 names of the people killed in Parkland, Florida. Then she waited. In determined silence. Staring straight into the crowd with tears rolling down her cheeks.

Through cheers and chants she held her silence. Then an alarm chirped.

“Since the time that I came out here, it has been six minutes and 20 seconds.”

Hundreds of thousands of people came out in the capital to demand action on gun control, and thousands more gathered in hundreds of sibling marches around the country and the world, from San Francisco to Cincinnati, from London to Houston to Parkland.

These 15 photos offer a glimpse of those marches—full of rage, sadness and ultimately hope.
