High school students across the United States walked out of their classrooms by the thousands in a show of protest and concern over gun violence on campus.
The coast-to-coast 'walk-out' comes a month after a deadly shooting in Florida, where 17 students and faculty members were killed, and another 17 were wounded.
Students chanted slogans like, 'no more silence' and 'we want change', as part of the National School Walkout.
