Students all over the country are taking part in walkouts to commemorate the 19th anniversary of the Columbine High School shooting. The action in memory of the 13 victims comes on the heels of the March For Our Lives, where hundreds of thousands of people gathered in Washington, D.C. to protest gun violence and lawmakers who refuse to restrict firearms. More than 2,500 schools are expected to have students take part. In Parkland, some students walked out while others stayed in school to take part in service projects.
