Tens of thousands of Coloradans filled Denver’s Civic Center Park on Saturday as part of the national March For Our Lives rallies for gun safety. Seventeen year-old Maddie King, a survivor of the Marjory Stoneman Douglas High School shooting in Parkland, Florida, was the keynote speaker. These are just a few of the images from the event.
