(AP/WPTV) - Students from Florida to Chicago started streaming out of their schools Friday in the latest round of gun-control activism following the February shooting at a high school in Parkland, Florida.

School walkouts were held at G-Star School of the Arts in Palm Springs, Atlantic High School in Delray Beach and Marjory Stoneman Douglas High School in Parkland.
"People shouldn't be able to buy guns without training, without experience," Brian, a Junior at G-Star School of the Arts said. "People should definitely not be able to add magazines who have multiple people in a matter of seconds."
Sarah, another student said, "I come from a family where almost everybody owns a gun because we're in the right mental state to own it, but for other people this is not the case."
The protests were chosen to line up with the 19th anniversary of the Columbine High School shooting, which left 13 people dead in Littleton, Colorado. At 10 a.m. in each time zone, students at dozens of schools left class to take moments of silence honoring the victims at Columbine and other shootings.
From there, some students headed to rallies at their statehouses. Others stayed at school to discuss gun violence. Some are holding voting registration drives.
Hundreds of Washington-area students gathered at a park near the White House, taking 19 minutes of silence for each year that has passed since the Columbine massacre. In New York City, crowds of students gathered in Washington Square Park and lay down in a "die-in."
Organizers say there will be walkouts in every state, with more than 2,700 registered on the event's website . Citywide protests are expected to attract thousands in New York City and Austin, Texas. Police in Richmond, Virginia, say they expect at least 10,000 at the state Capitol.
Shortly before the walkouts, another school shooting in Florida left one student injured. Authorities say one student shot another in the ankle at Forest High School in Ocala. A suspect was taken into custody.
At Marjory Stoneman Douglas High School, where a gunman killed 17 on Feb. 14, student David Hogg said the latest shooting underscored the urgency of the protests.
"We have to stop this. We're not going to be able to stop this unless we continue to make our voices heard, though, when our elected officials won't," Hogg said on a video posted to social media. "We have to get out there and make our voices heard, not as Democrats or Republicans, but as Americans."
Hogg was among about 50 students who walked out of Stoneman Douglas after administrators threatened protesters with unexcused absences.
Craig Smith and Terry McGary, both 17-year-old juniors, said they walked out because they want to show respect for the Columbine victims.
"It was a guilt trip to make us not walk out," McGary said about the threat.
Smith said gun violence can "no longer be swept under the covers."
"This is the only way to bring attention to the issue," he said.
The walkouts are the latest in a wave of youth activism that has emerged after the Parkland massacre.
Tens of thousands of students left class March 14 to protest gun violence in what historians called the largest youth protest movement since at least the Vietnam War. Days later, hundreds of thousands of teens and their backers rallied across the U.S. calling for tougher laws on guns and ammunition.
Plans for Friday's walkout began only hours after the Parkland shooting, when a Connecticut teen started an online petition calling for protests on the anniversary of Columbine. Sophomore Lane Murdock then gathered a few other students at Ridgefield High School to orchestrate the national protest.
They also have received help from Indivisible, a left-leaning nonprofit based in Washington that helps boost grassroots activism. The group says it was formed after the 2016 election to oppose the policies promoted by President Donald Trump.
"We're walking out to remember every single young person who has been killed by American gun violence," Murdock said in a statement Thursday. "We're walking out to talk about the real problems our country is facing, and the solutions that our leaders are too scared to dream up."
Administrators at many schools tacitly allowed the walkouts in March, opting not to punish participants. But some now say the leniency has expired.
At a town hall Monday, the chancellor of New York City's education department urged students not to walk out on Friday.
"You don't need to be out of school all day to make your voices known," Chancellor Richard Carranza told students at Brooklyn Technical High School. "You've already made your voices known. So I'm going to ask you to stay in school."
Some schools in Houston and elsewhere will give students time to share their views but have warned them not to leave campus or return to class late. Some others are holding alternative events after school. Many have simply said students are expected to stay in class throughout the day.
In Littleton, some survivors of the Parkland shooting joined Columbine students for a vigil and rally Thursday evening. But there will be no walkout at Columbine, which has long canceled classes on the anniversary of the shooting. Instead, students will be called to participate in a day of service.
Principal Scott Christy said in a letter to other schools in his district that April "has long been a time to respectfully remember our loss, and also support efforts to make our communities a better place."
