One month after a gunman killed fourteen students and three staff members at a school in Parkland, Florida, thousands of students from across the country from nearly 3, 000 schools participated in the National Student Walkout.  Facing the threat of detention, the students, armed only with picket signs, chants, and hope for change, walked of class for seventeen minutes, one minute for each of the victims of one of the most deadly school shootings in history.
