Parkland survivors weigh in on students' role in stopping school shootings

Three survivors of the deadliest school shooting in U.S. history are sharing their thoughts on a "close call" here in Vermont.

Emma González, David Hogg and Alex Wind attended Parkland High School in Florida, where a former student shot and killed 17 of his classmates.

We sat down with them Friday while they were in Burlington promoting their new book. In that interview we asked them about the foiled plot to shoot up Fair Haven Union High School in Vermont, which was uncovered just days after Parkland.

Tragedy was prevented here thanks to a friend who warned police. And "see something, say something" has been the motto from law enforcement everywhere.

While Gonzalez says it's important to speak up, the responsibility should not be placed on students.

"It's not anybody's responsibility to stop a shooting from happening. That's a police officer's job. Students should not have to be in charge of doing that, because a student's most important job is being a student, it's getting an education," she said.

The three are promoting their new book, "Glimmer of Hope," which features essays from students in the aftermath of the Parkland shootings.
