Updated April 21: Revised to clarify the students were off school grounds.

Students around Dallas-Fort Worth and the rest of the country walked out of their classrooms Friday in largely peaceful protests to call for legislation to end gun violence at schools.

After students from Frisco Centennial High School left campus, a brief fight broke out as a nearby resident confronted students and a videographer over noise from the protest.

Jesse Ringness, an independent journalist and Frisco resident, posted video of the incident on YouTube.

Warning: The following contains obscene language.

The footage shows dozens of students in a grassy area along a bike trail west of the campus, eating pizza and listening as their classmates speak.

About 3 1/2 minutes into the footage, a man is heard yelling, "Who's running this show?" The camera pans over to a bearded man in sunglasses and an American flag T-shirt complaining about the "[expletive] racket" and telling the students that they "need to go back to school."

The man says he has called in a noise complaint to police and tells the students they need to be more respectful of residents.

"Go protest somewhere else," he says.

The man then turns his attention to Ringness, 27, asking, "What is your deal?" and complaining about being followed.

He suddenly grabs the camera while Ringness repeats, "Don't touch my camera."

After about 40 seconds, the camera is knocked away. When the picture is restored, the bearded man is on the ground. One teenager punches him before others separate everyone.

A short time later, the man is seen talking to a police officer.

Ringness, whose monopod was broken during the incident, said that the students' walkout was completely peaceful for more than an hour, changing only when the man approached the protest.

"It's just too unfortunate it took a turn for the worse," Ringness said.

Ringness added that the student seen scrapping with the man was trying to defend him and that he thought the man was looking for an altercation.

"He was in the wrong but somehow claimed to be the victim in the end," Ringness said. "I think that's what he wanted all along."

Frisco police said that there was a disturbance at the walkout involving a homeowner and that it was resolved without any arrests.
