A judge ordered the release of footage from the Marjory Stoneman Douglas High School shooting that claimed 17 lives. The disturbing surveillance video serves as new evidence that the armed resource officer on the scene, Scot Peterson, remained outside while students were being shot at inside the school. 

Peterson contends that he responded to the gunfire by taking a tactical position. The video was released by the Broward County Sheriff’s office with the following statement: “The video speaks for itself. His actions were enough to warrant an internal affairs investigation, as requested by Sheriff Scott Israel on Feb. 21. After being suspended without pay, Peterson chose to resign immediately and retired rather than face possible termination.”

Peterson previously claimed that when he took that “tactical position,” he was not sure whether the gunfire was coming from inside or outside the building. It’s remains unclear if this was the video Sheriff Israel watched that “made [him] sick to his stomach.” As CNN reports, the video took longer than expected to be released, and they are trying to determine if this is indeed the footage that prompted Peterson’s suspension. CNN and other news organizations actually sued to obtain the video before a judge ordered its release.
