US nationwide students walk out in massive protest over gun violence

It's been exactly one month since the deadly shooting at Marjory Stoneman Douglas High School — and some are choosing a somber way to pay tribute to the 17 people killed in the Parkland massacre.

Thousands of students and teachers walked out of their classrooms on Wednesday as part of the #Enough! National School Walkout to raise awareness about issues of school safety and the impact of gun violence. The walkout last for 17 minutes to mark the 17 deaths in the Florida school shooting.
