A month ago, hundreds of teenagers ran for their lives from the hallways and classrooms of Marjory Stoneman Douglas High School, where 17 students and staff had been shot to death.

On Wednesday, driven by the conviction that they should never have to run from guns again, they walked.

So did their peers. In New York City, in Chicago, in Atlanta and Santa Monica; at Columbine High School and in Newtown, Conn.; and in many more cities and towns, students left school by the hundreds and the thousands at 10 a.m., sometimes in defiance of school authorities, who seemed divided and even flummoxed about how to handle their emptying classrooms.

The first major coordinated action of the student-led movement for gun control marshaled the same elements that had defined it ever since the Parkland shooting: eloquent young voices, equipped with symbolism and social media savvy, riding a resolve as yet untouched by cynicism.

“We have grown up watching more tragedies occur and continuously asking: Why?” said Kaylee Tyner, a 16-year-old junior at Columbine High School outside Denver, where 13 people were killed in 1999, inaugurating, in the public consciousness, the era of school shootings. “Why does this keep happening?”

A good question... why do these massacres keep happening?

Principals and superintendents seemed disinclined to stop them. Some were outright supportive, though others warned that students would face disciplinary consequences for leaving school. At many schools, teachers and parents joined in.
