But in Battle Creek, Michigan; in Bakersfield, California; in Toms River, New Jersey; in Iowa City, Iowa; and all over South Florida, the flickers of underage protest this week seemed to augur something new: a coast-to-coast challenge to the idea that the Snapchat generation was too young, too frivolous, for politics. "We definitely have a moral obligation to do something, considering that so many innocent people that we know passed," said Bishop's sister, Julia Bishop, 18. "These adults, these politicians, these legislators, they were supposed to protect us. And they didn't." Many of the protests around the country have arrived semi-spontaneously, apparently ignited by the impassioned pleas of young Parkland survivors in the hours and days after the shooting on February 14. Facebook and Twitter have amplified attendance; Snapchat and Instagram have documented the marches, signs and chants.

Still, the students have faced questions from some conservatives over whether they are being exploited. Bill O'Reilly on Tuesday asked on Twitter: "Should the media be promoting opinions by teenagers who are in an emotional state and facing extreme peer pressure in some cases?" One hour after news broke about the school shooting, Twitter accounts suspected of having links to Russia released hundreds of posts taking up the gun control debate.

Others used #gunreformnow and #Parklandshooting. The messages from these automated accounts, or bots, were intended to widen the divide and make compromise even more difficult.

In another sign of the deep entrenchment of guns, Bloomberg reported on Tuesday that a state pension plan for Florida teachers held more than $US500,000 in shares in the company that manufactured the semi-automatic AR-15 assault rifle used in the attack in Parkland. In Florida, an AR-15 is easier to buy than a handgun. For now, however, there is momentum. From South Florida to Bellingham, Washington, local walkouts were proliferating. A national event has been planned for March 14, one month on from the shooting, when students and teachers plan to leave class for 17 minutes - one minute for each victim. On March 24, students will protest in Washington at an event organised by March for Our Lives, the group formed by Parkland survivors, which has received hundreds of thousands of dollars in donations from celebrities. Another mass walkout is scheduled for April 20, when students will commemorate the 19th year since the Columbine High School shooting in 1999. The organisers of last year's Women's March are directing the March 14 walkout. Mostly, though, the adults have gotten out of the way. On Tuesday morning, hundreds of students from West Boca Raton High School in South Florida walked out of class and onto the roads, bound for Stoneman Douglas High, in a march that took Broward County officials by surprise. The authorities abruptly assembled a law enforcement escort for the students, said Todd DeAngelis, a city of Parkland spokesman. They also organised water stations along the way to help students, who walked nearly 18 kilometres, beat the heat.

"These kids may look like they're summer campers," said Paul Corin, whose daughter, Jaclyn, helped organise the Parkland caravan to Tallahassee. "But they are fierce warriors." In Bakersfield, California, about a dozen students and 80 adults marched on President's Day in support of stricter gun laws. The same day, more than 200 students in Iowa City marched out of school, walked to the Old Capitol downtown and gathered to read the names of the Parkland victims. "The NRA has got to go," they chanted. "Not one more." "At this point, you're either with us or against us," said Lujayn Hamad, a senior at West High School, according to The Iowa City Press-Citizen. "We are dying, and I'm not going to stand for it anymore." Some of the students of Toms River, New Jersey, also spent part of President's Day, a school holiday, massed on the steps of the squat, red-brick public library. A young man who described himself as a 16-year-old junior led the crowd in chants of "Enough is enough!".

"This is what it's come to," he said. "In this country, kids are typically expected to take a back seat to what goes on in politics and policy, and what's going on right now - it can't happen like that any longer." Accusing Congress and state legislators of inaction, he advocated stronger gun restrictions. The other option, he said, was turning schools into armed camps where "I have to be aware if there's a loud bang in the school, do I know where to go?". The adults who "have the responsibility to take care of these things" have failed, he said. "It's our generation's responsibility." On Tuesday, at least 20 students walked out of Harper Creek High School in Battle Creek, Michigan. The principal stood with them, and the district's superintendent was on hand. Students left class or held gatherings all over South Florida on Monday and Tuesday. There was American Heritage School in Plantation. Olympic Heights High School in suburban Boca Raton. Park Vista Community High School in Lake Worth. Fort Lauderdale High School in Fort Lauderdale. McArthur High School in Hollywood.

At South Broward High School, students aimed to participate in a protest almost every day to make their point. They started with a protest at their school in Hollywood last Friday, and then rallied in Fort Lauderdale on Saturday and at Hollywood City Hall on Monday, said Rachel Donly, a 16-year-old sophomore. "We don't think anyone is truly listening to us yet," said Donly, whose father is a teacher. "So we don't want to give up. We're just going to keep fighting." On the Parkland buses, pillows and sleeping bags had been crushed into the seats. Candy and doughnuts were passed from row to row. Laughter occasionally poked through. But the people the students were travelling for - their fallen classmates, coaches, teachers - were never far from their minds. Anthony Lopez, 16, a junior, was sitting alone in the back. He had scratched out a wish list he planned to deliver to legislators.

"Ban on military grade weapons (assault weapons, etc.)" he had written. "Universal background check, stricter," he had added. "Raise age for gun ownership (20+), unless for sport or hunting (16+)." Then the news arrived that the Florida House had refused even to consider a ban on assault weapons. How could they ignore the activism that had lit up social media, the students wondered. "They know that multiple kids, hundreds of kids, are coming up to the state Capitol, which by the way is extremely far, just to talk to them," Daniel Bishop said.

In the back, Lopez slammed his head back on the bus seat. He placed a hand on his forehead. "That's infuriating," he said. "They're acting inhuman." New York Times
