An armed school resource officer at Marjory Stoneman Douglas High School stood outside of the building and did "nothing" while a gunman opened fire on students and teachers, Broward County Sheriff Scott Israel said Thursday.
"Devasted," Israel said was his reaction at seeing video that showed the deputy taking a position outside the building, but never going in during the rampage that killed 17. "Sick to my stomach. There are no words."
Israel identified the deputy as Scot Peterson.
After surveillance video captured the deputy standing outside the building, Israel said he was placed on unpaid leave.
Peterson has since filed for retirement from the department.
