Newly-released surveillance video shows former deputy Scot Peterson standing outside Marjory Stoneman Douglas High School while Nikolas Cruz fatally shot 17 students and staff.
Broward County Sheriff's Office, which released the video, identified Peterson in the footage, adding that it "speaks for itself."
On afternoon of Feb. 14, Peterson, the school's armed resource officer, responded to the building where the shooting was unfolding within a minute and a half of when the gunfire started, Sheriff Scott Israel said. He positioned himself outside the building but never went in throughout the six-minute shooting, Israel said. Deputy Peterson resigned a couple of days after the mass shooting.
