The southeast lawn of the U.S. Capitol was covered in 7,000 pairs of shoes Tuesday, to symbolize the 7,000 children killed by gun violence since the shooting at Sandy Hook Elementary School in 2012.
The protest was arranged by the global advocacy group Avaaz.
According to Avaaz, the 7,000 deaths estimate is based on a statistic from the Centers for Disease Control that 1,300 children die from gun violence every year.
The shoes were donated by people across the country, including celebrities like Bette Midler, Susan Sarandon, Alyssa Milano, Chelsea Handler and Vanessa Bayer.
“It’s hard when you look at the scale, over 10,000 square feet of shoes on this lawn, and you’re just confronted by the consequences of not passing gun control laws,” Avaaz deputy director Emma Ruby-Sachs said.
