An advocacy group, Avaaz, placed 7,000 pairs of children's shoes on the lawn - each pair representing the life of a child killed by gun violence since the horrifying Sandy Hook Elementary School shooting in 2012 in CT.
To stage the protest, Avaaz crowdsourced the thousands of pairs of shoes from the families of the victims of gun violence and concerned citizens.
Explaining the meaning behind the installation, he said, "There's nobody in those shoes, it's like the emptiness in our hearts from gun violence".
"I think we're in the middle of a cultural change in the United States". But the president backed away from those proposals and instead outlined school safety measures this week favored by the National Rifle Association. Donors include actresses Susan Sarandon and Bette Midler, and talk show host Chelsea Handler.
"When students protest at schools, our school staff will respond appropriately and allow our students to be heard", said Robert Runcie, superintendent for public schools for Broward County, Florida, where Parkland's Marjory Stoneman is located.More news: Royal pay gap: The Crown's Claire Foy paid less than Matt Smith

Students all over the country plan to walk out of school for exactly 17 minutes at 10am local time to honor the 17 people who lost their lives at Marjory Stoneman Douglas High School.
The Parkland shooting was the deadliest school shooting since 26 were killed in 2012 at Sandy Hook Elementary School in CT.
The walkout has won the support of many school districts and civil rights organizations, including the American Civil Liberties Union.
"These kids, it's their lives". The shoes, all worn, were donated by thousands of people across the country, organizers said.
