About 7,000 pairs of children's shoes overtook the U.S. Capitol's lawn Tuesday morning.
The shoes were empty, but they carried a loaded message: Each pair represents a child killed by gun violence since the Sandy Hook school shooting in December 2012, claims Avaaz, the activist group that arranged the protest. The New York Times reported last month that in 239 school shootings since Sandy Hook, 138 people have been killed.
After the protest wraps up at 2 p.m. ET Tuesday, the shoes will head to homeless shelters in Washington, D.C. On March 24, the March For Our Lives, organized by the student survivors of the mass shooting at a Florida high school last month, will bring its gun reform message to the nation's capital.
