Friday morning, dozens of students at Lubbock High School left their classrooms to protest gun violence, remember victims and push for common sense gun laws.

The event, which took place on the 19th anniversary of the school shooting at Columbine High School in Colorado, was publicized earlier this week via social media. Students who wanted to take part in the event were asked to be respectful.

"We'll stand in silence honoring those lost to gun violence and advocating for common sense gun laws," a flyer for the event read.

At one point in the event, which featured several speakers, the crowd began chanting, "we want change."

Not everyone was supportive of the students' walkout and push for new gun laws.

On Everything Lubbock's Facebook Live video of the event, many viewers criticized the students.

"Just a bunch of paid puppets that have no clue what they are out there protesting about," wrote one person. Another said that the protesting students should be sent to jail. Many accused the students of just wanting to get out of class, and one person called them "sheep."

A few people, however, were supportive of the students.

"It's the 19th anniversary of the Columbine High School shooting in Littleton, Colorado. It’s an appropriate date to stage a peaceful protest," wrote one person. "I'm proud of the young citizens of this city."

Students who participated in the walkout also learned that there are consequences for your actions: they received an unexcused absence for 3rd period.
