CLEAN : A sea of empty shoes at the US Capitol in gun protest

The video highlights a poignant protest on the Capitol lawn in Washington DC, where 7000 pairs of children's shoes are displayed to honor the 7000 children killed by gun violence since Sandy Hook in 2012. The empty shoes symbolize the lives lost and serve as a powerful reminder of the need for action against gun violence. The video criticizes the NRA's proposal to arm teachers, suggesting it is a distraction to sell more guns rather than protect children.
