The Broward County Sheriff’s Office released surveillance video showing what happened outside Marjory Stoneman Douglas high school during the Valentine's Day massacre that killed 17 people. Authorities say the video from outside the school depicts actions during the shooting by former deputy Scot Peterson, who was armed and assigned to the school but did not enter the targeted building during the shooting. Sheriff Scott Israel of Broward county said Peterson was suspended without pay, and chose to resign.
